Can fingertip blood collection check platelets?

Blood type refers to the type of antigen on the surface of blood components (including red blood cells, white blood cells and platelets). It is worth noting that ABO blood group system can only be simply judged in the preliminary screening, and Rh blood group system requires blood samples to be sent to the blood testing department of the blood station for testing.

Hemoglobin test is an item of blood screening during blood donation. According to the "health examination standard for blood donors" formulated by the Ministry of health of the people's Republic of China, hemoglobin (HB) determination: female ≥ 115g / L, male ≥ 120g / L; Or the proportion of blood in female ≥ 1.0510, male ≥ 1.0520 can donate blood.

Transaminase is a "barometer" of the liver, and liver cells are the main habitat of transaminase. When the liver cells are inflamed, poisoned and necrotic, the liver cells will be damaged, and the transaminase will be released into the blood, which will increase the serum transaminase. Single serum ALT level can not judge the degree of liver damage alone. At the same time, transaminase is also a very sensitive index. Some blood donors stay up late and drink alcohol before blood donation will also affect the transaminase, which is also the reason why some blood donors are told that they need to rest for a few days when they find themselves unqualified in the initial screening.

The reason why the inner ring finger is often used in blood collection is, on the one hand, because the hand is the bare part of the human body, which is the most flexible and easy to operate. On the other hand, there are abundant capillaries in the finger tip, but there are no large arteries and veins to avoid massive bleeding.
