Most tubes of blood used by clinical laboratories hold 5 cc of blood (1 tablespoon). By comparison the average human body has 5 liters or 5,000 cc of blood which is 1.2 gallons. Thus, drawing a few tubes of blood is of no consequence for the vast majority of patients. Tubes come with stoppers in various colors. The color of the tube stopper designates the specific preservatives in the tube. There are more than 30 types of tubes available. Different tests require different preservatives.

The pint of blood you donate will be separated into three components; red blood cells, plasma and platelets. If needed, two additional components may be made from a pint of blood: cryoprecipitate and white blood cells. The blood components are then stored until it is needed.

A group of tests that are important for diagnosing lupus will be performed. The results of these tests (serology) will be sent to you if you choose to receive them. The DNA in your blood will be analyzed to determine which genes may be involved in lupus and to address other scientific questions about lupus as they arise. A permanent cell line will be established and this cell line may be used for other approved lupus research at a later time.

You can give blood every 56 days (8 weeks). Every time you donate, you will have to meet the same criteria as you did before, and pass the medical examination.

After you have given blood, it is stored at a temperature of 2-5?C and undergoes a series of tests to rule out the presence of hepatitis B or C, or the AIDS virus, and the reaginic test for syphilis is carried out; ABO and Rh blood groups are also determined, and irregular antibodies are analysed. The bag of blood is separated by centrifugation into different components: from one bag, we obtain red blood cell concentrate, platelet concentrate, and one unit of plasma.

However, taking blood tests during fasting is permissible and that does not invalidate the fast.
