Description
[0030] Specific embodiments of the invention are now described with reference to the accompanying drawings wherein:
[0031]
[0032]
[0033] Referring firstly to
[0034] The body also includes a portion 6 which can be exposed to a sample of bodily fluid from the person or animal such as blood, serum, extrudates, saliva, sputum, pleural effusion, urine or the like and which leads to the antibodies using lateral flow techniques. The apparatus also means such as a scanner 8 or biomarker signature, also known as biomarker signature, detection means 10 to allow a unique ID to be generated for the patient or animal on which the test is being performed using that item of apparatus 2.
[0035] Once the sample has been received on the apparatus as indicated by step 12 in
[0036] The biomarker molecules required in order to perform the particular test for which the apparatus is provided, are identified and then prepared in quantity via current best practice such as via expression, purification, synthesis or the like. These biomarkers then become the antigen component for the development of antibodies such as monoclonal or polyclonal antibodies which are themselves unique to the biomarker.
[0037] The antibodies can then be provided in the apparatus 2 in an immobilised condition on a suitable carrier, such as gold nanoparticles but could be another suitable carrier such as magnetic beads or the like. The immobilised particles are incorporated into the disposable point of use diagnostic test apparatus 2 and is based on the principles of immunochromatography and typically a lateral flow test strip.
[0038] When the unique biomarker from a sample under test (the analyte) comes into contact with an antibody on the test strip, it gives a visible signal which is measured by the test reading device. This signal identifies the biomarker and the resulting data uploaded to the diagnostic test system.
[0039] The number of lanes on the test strip depend upon the number of biomarkers needed for the unique test.
[0040] The test data 14 from the apparatus 2 is transmitted from the apparatus 2 via a communication transceiver located in the apparatus body 4 or alternatively via an external apparatus such as a mobile phone to which the apparatus can be connected, wirelessly or via cable connection to a remote database 16 and can then be compared to validated database control parameters to determine the status of the condition with reference to the test ID and the provision of the communication means allows the said data relating to the identifier and/or further data from the particular test apparatus to be uploaded to the database.
[0041] The apparatus 2 typically allows the diagnostic test to be based upon the identification of a unique biomarker signature using low-cost, rapid point of view, test mechanisms. A key feature of the biomarker signature is a number of biochemical biomarkers which are associated with the disease and the number of the same can be from one, to tens or more, depending upon the disease and the identifications which need to be made. These are identified via a specialist “omics” research and typically will be a metabolomic biomarker, proteomic biomarker, lipidomic biomarker or the like. It is the ability to identify the signature in addition to the series of biomarkers associated with the health condition to which test relates, which is an important aspect of the invention.
[0042] The test result data is then compared to the validated database control at stage 18 to determine the status of the condition and this is a diagnostic stage which allows the detection of the health condition status to be performed for the specific person or animal on which the test was performed.
[0043] The status of the condition 20 is identified and the result can be transmitted 22 to the user who may be the patient or carer who typically, will still be on site and can therefore undertake any recommended immediate action, if necessary. Furthermore, the data relating to the health condition can be uploaded 24 along with the status determined by the test, to a clinical and/or other secure database 26 along with a unique user identification such as a tag, number, barcode, QR code, or a biometric identification so as to uniquely associate the diagnostic test with a sample and the user, patients, animal, clinical practitioner, veterinary practitioner and/or the like.
[0044] The secure database 26 encrypts and stores the unique test and identification data so that the data can then be interrogated and associated with other metadata using algorithms to compute a decision process in relation to the condition to enable it to be actioned and managed.
[0045] By enabling the encrypted data and actions from the decision process algorithm to become accessible on the internet via, for example, cloud hosting 28 to other secure users, the rapid dissemination of information, actions and decisions regarding the condition can be achieved which, in turn, facilitates remote identification and control of the condition.
[0046] Typically, the method includes machine learning and artificial intelligence because of the intelligent algorithms which are used. As the data and metadata database increases for any condition, the decision making, which, without this system in a clinical setting, can only be made by qualified practitioners and specialists, can ultimately be taken by the system, hence reducing the burden on the specialist and generation of random errors. This integrated intelligent analysis system in accordance with the invention therefore allows the data to be taken from each test, interprets the result, links it to other data from, for example, a specific animal or patient, and provides, from this, a series of decisions and/or actions which can, if required be relayed immediately to the person on whom the test has been performed and/or the person performing the test.
[0047] Management and control elements can be used, for example, in disease management for human and animal diseases, food chain management and farming etc. The current process therefore simplifies the analysis of large amounts of data by using machine learning and powerful artificial intelligence techniques with bioinfomatics. The data is analysed in terms of specific data and patterns of data that are unique to a person and/or animal and can be used to address the manner in which these conditions are currently dealt with and may be in the future.
[0048] Furthermore, the method allows the generation of actions and specific treatments which are specific to a person or animal at that time and therefore the treatments can be made more precise to every person and can be monitored subsequently. Patient target therapeutics is therefore possible in accordance with the invention and is performed as a result of tests using low-cost and disposable, rapid test apparatus using lateral flow technology at the point of care of the person or the animal. Due to the fact that the tests can be performed quickly and cheaply, then the same can also be performed more frequently without a significant increase in cost and the use of the secure database information technology, along with intelligent algorithms, allows the data to be used to provide immediate feedback to the clinician, person and/or animal along with the information to decide on the correct course of treatment.
[0049] The provision of these person or animal targeted therapeutics enables clinicians to understand and correctly treat the patient, allows drug companies to target their existing products and speedup the clinical evaluation of new drug entities, avoids incorrect and unnecessary prescribing of drugs and allows the health provider to save monies which otherwise would be spent on nontargeted patient care and avoids the environmental impact of overuse of unsuitable drug treatments. Thus, there is provided in accordance with the invention, a diagnostic toolkit, a monitoring system for dynamic changes in the disease and/or the person or animal condition and a guiding system for precision treatment of the health condition.
[0050] Specific examples of the use of the invention are provided as follows:
[0051] With regard to Chronic Obstructive Pulmonary Disease (COPD) the diagnostic test is carried out at the point of care and is read by the diagnostic test apparatus. The data is captured by the portable test reading device and the results data is transmitted to a remote database, typically using cable or wireless communication means for analysis. After analysis, the patient is advised of the actions required and their carer is notified simultaneously by the system. The risk assessment, decision process and actions are determined and verified with the person, carer, GP, specialist or hospital as required and the data is typically also uploaded to a secure cloud data system for subsequent interrogation and are computed by intelligent algorithms and provide a learning capability which ultimately leads to the completion of the patient's specific personalised companion diagnostic toolkit. This integrated technology is the point of use/care Detect, Manage and Control (DMC) system. For example, with COPD, if a patient is about to have an exacerbation (the specific biomarkers will be apparent before the exacerbation occurs) then by linking the biomarker signature for a specific patient to all the other patient data, a diagnosis and action plan can then be advised to the patient without the need for a consultant intervention. The actions may include for the person to attend hospital immediately, in which case the suitable clinical unit is advised in accordance with the invention to prepare to receive the person. Another action may be to use the biomarker signature and analysis in order to allow the identification, through the data interpretation, patient data and specific pharmacological data, and thereby advise as to the type of treatment actions which should be taken and/or administered.
[0052] In another example of the invention, with regard to testing for bovine tuberculosis (bTB), the diagnostic test is carried out at the point of use by a trained veterinary technician/practitioner/farmer because it involves taking a suitable sample from the animal, such as blood. The blood sample is applied immediately to the portion of the body of the apparatus such as a disposable lateral flow test portion. The said portion can then be inserted into analysis means in the form of a diagnostic test device. The animal being tested has a unique identification tag which is read by the diagnostic test reader such as optical character recognition/barcode or QR code and the data from the diagnostic test is captured by the portable apparatus and this is uploaded to a secure database along with the unique ID so that the test data is associated with other data regarding the animal on which test has been performed such as the farm, location etc. Once the diagnostic test and verification of the animal is concluded, the result is notified to the user and can be uploaded to a cloud database for information, notification, action by the farmer and veterinary authorities as appropriate. The data uploaded to the secure cloud data system can be interrogated and computed by intelligent algorithms with its learning capability, along with the track-and-trace via the unique tag can associate the specific animal to all activities and actions along with food chain. For example if the test result shows a presence of tuberculosis the animals and farm linked to the test animal may be sanctioned and this is identified on the general database.
[0053] Thus the test method and apparatus has herein defined can have significant and far reaching benefits, for example, continuing with the reference to bTB, with the key biomarkers associated with the disease identified so the next stage is antigen/antibody preparation and then binding these antibodies to the glod particles for the lateral flow test strip of the apparatus.
[0054] A number of important features can emerge from the biomarker identification and in this example the biomarker identification is so specific for mycobacterial infection, that by using this one alone one can determine infection with a sensitivity and specificity of >95%—for bTB testing in cattle which is a major step forward and a breakthrough in terms of testing because the current mandated test which uses tuberculin in a skin test not only has a sensitivity of less than 60% (range 40-75% with a lot of variables) but takes 3 days to get a “result” As the “sensitivity” of the test determines the number of false negatives so it is possible with the conventional test that up to half the cows tested “pass” the test but are actually infected and so go back to the herd and as soon as they get stressed/ill (which is very common in high intensity dairy farming) infection increases again.
[0055] The government want to introduce a vaccination programme to resolve this (now committed to eradication by 2038) but this is dependent upon a test which can differentiate between vaccinated and infected animals (DIVA)—otherwise vaccination cannot be implemented. In the current invention the identification of the relevant biomarker is important in this respect as it is also DIVA so we have the possibility of a rapid, accurate and highly sensitive test which also differentiate between infected and vaccinated animals
[0056] Specifically for bTB, the government strategy will also rely on the vaccination of badgers because although badgers (and other feral animals eg deer, boar, etc and dogs do get infected and act as transmission vectors, the main transmission is between themselves and in the cattle herds themselves. Currently there is no practical solution for implementing a vaccination programme for badgers because if they are trapped they need to be tested before determining infected or not (which takes 3 days with the standard test) if infected they get culled, if not, vaccinated and released. The apparatus and test method of the current invention resolves this problem.
[0057] Furthermore the biomarker signature which has been identified is valid also for human TB.
[0058] Typically, all human and animal diseases, as well as any diagnostic tests requiring full traceability, security, integrity, ability to be interrogated and required for bioinformatics e.g. microbial tests for transmittable diseases, biometric fingerprinting, food chain traceability and control benefit from the invention.
[0059] Typically the portion of the apparatus which comes into contact with the sample, such as a lateral flow test portion may be specifically designed for the particular purpose in terms of the type of disease to be tested and/or the risk category of that disease to the person performing the test so as to provide the appropriate masking and protection for them and/or the “type” of person who will be performing the test. i.e. whether they are a health professional, such as a doctor vet, or a non-professional, such as a farmer, carer or the like and with the aim being to enable the test to be performed efficiently and reliably, regardless of who performs it and thereby minimise the risk to the person performing the test. Typically, in whichever form, the body or at least the portion of the body which contacts with the sample will be a single use disposable component.
[0060] Typically the apparatus for use on site will be provided to be a hand held body and in addition to the said sample test portion may include any/or any combination of means to receive manually input alphanumerical data, scan barcodes, capture photographic images, perform image recognition, read the test result, possibly store the test result at least on a temporary basis, transmit the data to a remote location such as a cloud database and/or receive data from the subsequent analysis which is performed and will typically have a display screen to allow user interaction with the same.
[0061] Thus, in accordance with the invention, there is provided a biochemical biomarker signature for each individual diagnostic test and the individual biomarkers (analytes) and their antibodies. The diagnostic test system algorithms which calculate the outcome of the biomarker assay and report the result will typically derive statistically from validated data to determine the sensitivity and specificity of the assay.
[0062] Typically therefore the current invention allows the identification of biomarker signatures relating to the animal or human on which the test has been performed and which are linked to a specific disease in relation to which the test is performed and also in relation to a particular stage of the disease.
[0063] This also allows intelligent learning to be performed so that the associated data and metadata can be used to build a knowledge base for where the disease is prevalent, whether there are trends related to location, farm practice, transportation, lifestyles, environments or any combination of these and regardless of whether the apparatus and method is used in relation to animals or humans.
