Why Are Blood Tests Important?
Blood tests help doctors check how well your body is functioning. They can detect infections, monitor chronic conditions, assess organ health, and even identify nutritional deficiencies. By understanding your blood test results, you can have more informed discussions with your doctor about your health.
Common Blood Test Abbreviations and Their Meanings
Here’s a list of frequently used blood test abbreviations and what they stand for:
1. CBC (Complete Blood Count)
This test measures different components of your blood, including:
RBC (Red Blood Cells): Carry oxygen in your body. Low levels may indicate anaemia.
WBC (White Blood Cells): Fight infections. High levels may suggest an infection or inflammation.
Hb or Hgb (Haemoglobin): A protein in red blood cells that carries oxygen. Low levels may mean anaemia.
Hct (Hematocrit): The percentage of red blood cells in your blood. Low levels may indicate blood loss or anaemia.
PLT (Platelets): Help with blood clotting. Abnormal levels may affect bleeding or clotting risks.
2. LFT (Liver Function Test)
Checks liver health by measuring:
ALT (Alanine Aminotransferase): High levels may indicate liver damage.
AST (Aspartate Aminotransferase): Elevated levels can suggest liver or heart issues.
ALP (Alkaline Phosphatase): High levels may indicate bile duct problems or bone disorders.
Bilirubin: A waste product processed by the liver. High levels may cause jaundice.
3. KFT (Kidney Function Test)
Assesses kidney health by measuring:
BUN (Blood Urea Nitrogen): High levels may indicate kidney problems.
Creatinine: A waste product filtered by the kidneys. High levels suggest poor kidney function.
eGFR (Estimated Glomerular Filtration Rate): Measures how well kidneys filter waste.

Tips for Managing Abnormal Blood Test Results
If your results are outside the normal range, don’t panic. Some fluctuations are normal, but it’s best to consult your doctor. Here are a few general tips:

For High Blood Sugar: Limit sugary foods, maintain a healthy weight, and stay active.
For Low Haemoglobin (Anaemia): Increase iron-rich foods (spinach, lentils, red meat) and vitamin C (helps iron absorption).
For Liver/Kidney Issues: Avoid alcohol, stay hydrated, and follow a balanced diet.
