Full Blood Count (FBC)
Full blood count determines general health status. It is used as a screen for a variety of disorders, such as anaemia and infection, inflammation nutritional status and exposure to toxic substances.
Erythrocyte Sedimentation Rate (ESR) CRP (C- reactive protein)
Both tests are not specific enough to diagnose a particular disease; they do however serve as general markers for infection and inflammation. CRP is a marker of infection and inflammation, which can alert medical professionals that further testing and treatment may be necessary. High sensitivity CRP (hs-CRP) is another marker related to risk factor evaluation of ischemic heart disease.
Iron levels
Low iron can cause anaemia, and is usually due to long-term or heavy bleeding, pregnancy, or rapid growth (in children); rarely is it due to poor diet. A high iron level can be due to a genetic condition, extensive blood transfusions, or rarely due to ingestion of an overdose of iron (usually in children).
Ferritin, TIBC
Usually requested in the investigation of anaemias.to see how much iron your body has stored for future use. The test is done, usually with an iron test and the total iron binding capacity (TIBC).
The test may also be requested when there is suspicion that you have too much iron, for example in haemochromatosis (a disease in which too much iron is absorbed from the diet) and eleveted levels are also encountered in neoplastic disease.
Folate and B12
Usually requested in the investigations of anaemia as they are a precipitating cause.
Patients with an early deficiency may be diagnosed before they experience any overt symptoms. Other affected patients may experience a variety of mild to severe symptoms that can include:
