Problems solved by technology

[0014] The above-mentioned invention patents are all blood cell diluents, which are used to protect cell morphology, including cell structure, but do not protect other proteins and chemical components in the blood. Some inventions even destroy some red blood cells, which affects the detection results during the detection process. , this is not the problem that the present invention finally intends to solve

Abstract

The present invention relates to a reagent for processing trace whole blood and an application thereof. The reagent comprises the following components: a buffer solution, an osmotic pressure retaining agent, a protective agent, an anticoagulant, and a preservative. By using the reagent provided in the present invention, the following can be achieved: a trace whole blood sample is diluted and treated by any times (2 to 1000 times) to obtain dilution of serum or plasma without damaging the sample and without causing erythrocyte hematolysis.

Description

technical field [0001] The invention relates to a whole blood reagent, in particular to a reagent for processing a small amount of whole blood and its application. Background technique [0002] At present, clinically, most of the detection items of blood samples (such as the detection of 25-hydroxyvitamin D3, the detection of two-and-a-half hepatitis B, etc.) use serum or plasma samples, and the way to obtain serum samples is to collect veins first. For blood, centrifuge after taking the blood, and absorb the supernatant for detection; the method of obtaining plasma samples is to collect venous blood with a blood collection tube containing an anticoagulant, then centrifuge after taking the blood, and absorb the supernatant for detection. However, the existing preparation methods all collect venous blood, then centrifuge the whole blood to separate serum and plasma, so the amount of blood needed is relatively large. [0003] There may be some special groups among the people ...
