Blood tests are one of the most common diagnostic tools used in healthcare. They can reveal important information about your overall health, help diagnose conditions, and monitor ongoing treatments.
Common Blood Test Markers
When you receive your blood test results, you may see various markers and values. Here are some of the most common ones:
Full Blood Count (FBC) - This measures different components of your blood including red blood cells, white blood cells, and platelets. It can help detect anaemia, infections, and blood disorders.
Liver Function Tests (LFTs) - These measure enzymes and proteins produced by the liver, including ALT, AST, ALP, and bilirubin. Elevated levels may indicate liver damage or disease.
Kidney Function Tests - Creatinine and urea levels help assess how well your kidneys are filtering waste from your blood.
Lipid Profile - This measures cholesterol levels including total cholesterol, HDL (good cholesterol), LDL (bad cholesterol), and triglycerides.

Each blood test marker has a reference range, which represents the values found in most healthy individuals. These ranges can vary slightly between laboratories.
If your results fall outside the reference range, it does not necessarily mean you have a health problem. Many factors can affect results, including:
