If you want your relatives to donate blood, you don't have to pay blood donation card to the blood vessel. It seems that friends can't.
Hospitals, vascular offices and blood stations are from different institutions under the Health Bureau, right? Hospitals and blood stations are not from the same institution, so blood and hospitals should be bought from blood stations. The money from the blood station should be turned over to the health bureau. The raw materials and labor costs of blood station inspection equipment, reagents, etc. are allocated by the government, not the money sold to the hospital after blood drawing. After blood drawing, it is necessary to go through a round of various virus tests before qualified blood can be sold to hospitals.
2 ml of red blood cells may be 12 yuan? A few years ago, I forgot. Hospital blood money and blood vessel money are the same price, it seems.
platelets are collected by machine, because the equipment is disposable, the price is relatively expensive, which seems to cost more than 1 yuan.
non-provincial cities are generally blood stations, and provincial capitals are generally blood centers. Blood donation card can only be used in a city to collect blood. But if you donate blood in Shanghai, blood donation card can be used all over the country.
If the patient is RH-negative, the price of blood is twice that of ordinary blood, and RH-negative is hard to find. Maybe one person in 1 people is RH negative, so the blood bank may store only a few bags.
