The normal range for Liver Function Tests (LFTs) varies depending on the specific parameter being measured. Here's a breakdown of the normal ranges for common LFT parameters, as provided by the reference:
Common LFT Parameters and Their Normal Ranges
| Parameter | Normal Range |
|---|---|
| Total Protein | 6.4 to 8.3 gm/dl |
| Serum Albumin | 3.5 to 5.2 gm/dl |
| Serum Globulin | 2.0 to 3.5 gm/dl |
| Albumin / Globulin (A/G) Ratio | 1 to 2 |
Understanding LFT Results
- Total Protein: Measures the total amount of protein in the blood.
- Serum Albumin: Albumin is a protein made by the liver.
- Serum Globulin: Globulins are a group of proteins in the blood.
- Albumin/Globulin (A/G) Ratio: This ratio is calculated by dividing the amount of albumin by the amount of globulin in the blood.
It is important to note that normal ranges can vary slightly between laboratories, and results should always be interpreted by a healthcare professional in the context of an individual's medical history and overall health. An abnormal result does not always indicate a liver problem.
