The invention relates to a
platelet preserving agent, which has the following constituents (by weight percent): dipotassium EDTA: 10-14%,
sodium citrate: 6-10%, Novocain:0.45-0.55%,
Polyvinylpyrrolidone: 0.46-0.50%, polyethyleneglycol 6000: 0.48-0.52%,
adenosine triphosphate: 0.03-0.07%, heparan: 0.005-0.015%,
prostacyclin: 0.005-0.015%,
urokinase: 0.01-0.03%,
plasmin: 0.005-0.015%,
adrenomedullin: 0.01-0.03%,
hydroxyethyl cellulose sodium: 0.15-0.25%, JNSO-2000 long-acting
antimicrobial agent: 0.05-0.15%, and water: the residual amount. The
platelet preserving agent preparation method provided by the invention has the following steps in sequence: proportioning main raw materials and performing ultrasonic wave action, adding
protein material liable to lose the activity and uniformly mixing, performing suction
filtration and preparing. The
platelet preserving agent provided by the invention enables platelets to maintain the
stable state of individual distribution within 24 hours after leaving the body and have no statistical variation within 24 hours, thereby ensuring the accuracy in
blood cell analysis. The platelet preserving agent preparation method provided by the invention has the remarkable implementation effect contrasted and verified by testing.
