When to Get Tested?

When a patient is anaemic without an obvious cause and/or has a condition or cancer that may be affecting blood cell production; as a means of helping find out how advanced a cancer is; sometimes when a doctor is investigating a fever of unknown origin, especially when the patient is immuno-compromised

Sample Required?
