The present disclosure relates to a capillary blood collecting device which includes a fixing device including an accommodating cavity for accommodating a blood collection finger and a squeezing member for squeezing blood to a fingertip site. The capillary blood collecting device is configured to detachably accommodate at least one skin puncture part on a blood collection side of the finger, and the skin puncture part includes a blood lancet that may be driven to puncture the blood collection finger, such that a sufficient amount of capillary blood quickly flows out from the capillary blood converged at the fingertip under the action of blood lancet.

A method of predicting whether an MDS patient has a good or poor prognosis uses a general purpose computer configured as a classifier and mass-spectrometry data obtained from a blood-based sample. The classifier assigns a classification label of either Early or Late (or the equivalent) to the patient's sample. Patients classified as Early are predicted to have a poor prognosis or worse survival whereas those patients classified as Late are predicted to have a relatively better prognosis and longer survival time. The groupings demonstrated a large effect size between groups in Kaplan-Meier analysis of survival. Most importantly, while the classifications generated were correlated with other prognostic factors, such as IPSS score and genetic category, multivariate and subgroup analysis showed that they had significant independent prognostic power complementary to the existing prognostic factors.

This invention relates to an apparatus and a method for measuring whether organic matter is present or whether or not organisms (cells or tissue) are alive using infrared absorption spectroscopic analysis. The measurement apparatus of the invention includes an infrared light source for radiating infrared rays on a sample, an infrared detection unit for detecting the infrared rays transmitted or reflected from the sample, and a determination unit for identifying an amide infrared absorption peak of the sample using the detected infrared rays and for determining whether organic matter is present or whether organisms are alive or not in the sample using the identified amide infrared absorption peak. In this invention, a reagent is not used, simple measurement is performed, quantification is feasible, and the presence or absence of cells or tissues and changes in the life and death can be consecutively measured for the same sample.
