Problems solved by technology

At present, the production of whole blood quality control materials is mostly prepared with finished bank blood. The main components of maintenance bank blood are citric acid, sodium citrate, glucose, sodium dihydrogen phosphate, and adenine; the fixative is a single component glutaraldehyde , easy to cause platelet aggregation and changes in cell morphology, the maintenance time is generally 1 to 3 months, and the stability is poor
Chinese patent 1263200 discloses a hematological cell three-differentiation whole blood quality control substance, which uses poultry blood and hoofed animal blood to replace white blood cells and platelets in the quality control substance respectively. Due to the basic effect with clinical samples in actual work, the histogram The picture shows that different from clinical specimens, the indoor quality control results may be good, but the instrument status is not under control
On the other hand, the production process is the production and recombination of single components (red blood cells, white blood cells and platelets), the production steps are cumbersome, the blood is easily polluted, and it is a suspension, which is not easy to be uniform and needs to be stirred, which is not conducive to the protection of the cell membrane and is easy to cause accidents.
