The harm of platelet donation

In fact, the composition of blood donated by the human body is basically the same as that of whole blood, which is harmless to the human body, and it can return to the pre harvest level 48 hours later. The donor can donate once every month, and the platelet recovery is very fast. Moreover, if you donate 800 ml of whole blood, you can enjoy unlimited free blood for life, and your immediate family members (parents, spouses, children, parents of spouses) can enjoy the same amount of free blood.

Generally speaking, donating a therapeutic dose (10u) of platelets is as common as donating whole blood, which has no effect on people's health. There are 100 ~ 300 × 109 / L platelets in normal human body. The life span of platelets in vivo is 8-11 days, but the life span in vitro is shorter. The daily renewal rate of platelets is (35.0 ± 4.3) × 10%. However, only 2.5 ~ 5.0 × 1011 platelets are donated each time. The recovery of platelets is faster than that of red blood cells. Three days after the platelets are donated, the platelets in circulating blood will return to the level before donation, so it is not necessary to pay attention worry.

Platelets recover very quickly. The life span of platelets in the human body is only about 10 days. Even if they are not donated, they have to be replaced. The reference value of platelet count in healthy people is between 100 and 300. Platelet count should be detected before blood donation to ensure that it is not less than 100 after donation. After donating platelets, the platelets in the body are enough even if bleeding occurs.

matters needing attention

The harm of donating platelets is not big. As long as your body is healthy, there will be no problem. After blood donation, the blood calcium in the body will not decrease. After one day of machine collection, nothing will happen.
