A computer-implemented method for interpreting an electrochemical response, comprises the steps of: (a) providing an electrochemical response that is baseline-corrected; (b) identifying in the electrochemical response one or more peaks that exceed a predetermined height threshold and a predetermined prominence threshold, each identified peak having a peak position; (c) providing a predetermined peak position range for each of a plurality of analytes; and (d) attributing one or more of the analytes to the peaks identified in step b, by, for each peak, associating the peak with an analyte when the peak position falls within the predetermined peak position range for the analyte.

The invention concerns an analyte meter (10) for medical tests having a meter housing (12), a strip port (14) mounted in an opening of the meter housing (12) and configured to receive a measuring part of a test strip (18), and a sealing insert (16) which is arranged within the strip port (14) and provides an insertion path for the test strip (18). For improved screening against contamination, it is proposed that the sealing insert (16) comprises a plurality of sealing elements (42) which are arranged consecutively along the insertion path, wherein each of the sealing elements (42) has a slit (46) that forms a sealed aperture for the test strip (18) to pass through.

Methods and techniques are described for analyzing test fluids to determine presence, absence, or concentration of analytes in the test fluids. The methods may correspond to diagnostic testing, such as quickly (within 5 minutes) identifying whether or not an individual may have a particular disease or condition, such as infection by SARS-CoV-2 or a SARS-CoV-2 variant or vaccine-induced immunity or natural immunity to infection by SARS-CoV-2 or a SARS-CoV-2 variant, or whether an individual would benefit from a vaccine booster. The test results can be used for a variety of applications including facilitating or controlling access at events, venues, or transportation systems, or generating exposure notifications.

A method and system for determining a failsafe value for a biosensor having two perimeter electrodes, a distal electrode, and a proximal electrode are disclosed. A liquid measuring medium is applied to a capillary channel of the biosensor.
