There are about one billion red blood cells in two or three drops of blood.
You will need to discuss the infection with our Staff. For most infections acquired in the community we will ask you to wait until 7 days after full recovery and after stopping antibiotic treatment, if used.
In the case of some infections we will ask you to wait for longer, e.g. rubella 4 weeks, and after cytomegalovirus (CMV) or glandular fever (EBV), we will ask you to wait for 6 months.
Chronic virus infections such as chronic hepatitis B, hepatitis C and HIV will prevent you from giving blood. If in doubt, please discuss with our Staff.
If a person has low iron levels in the body it is not appropriate for them to donate blood. If iron tablets have been prescribed by your doctor, you need to wait or 6 months before you can next give blood.

Vitamin tablets taken as a dietary supplement are OK.
If you are well at present and have had no symptoms in the past month you may donate.
Our Staff will discuss whether or not you may have ulcerative colitis or other inflammatory bowel disease such as Crohns Disease.
