The safe range for ALT (SGPT) typically falls between 7 to 56 units per liter (U/L) of blood in adults. This range provides a general guideline; however, optimal levels can vary slightly depending on the laboratory and individual factors.
Understanding ALT (SGPT) Levels
ALT, or Alanine Aminotransferase (also known as SGPT, Serum Glutamic Pyruvic Transaminase), is an enzyme primarily found in the liver. Measuring ALT levels in the blood is a common liver function test. Elevated levels can indicate liver damage or disease.
Normal ALT (SGPT) Range
| Test | Normal Range (U/L) |
|---|---|
| ALT/SGPT | 7-56 |
Note: These values are general guidelines, and specific lab ranges may vary.
Factors Affecting ALT Levels
Several factors can influence ALT levels, including:
- Age: Normal ranges can vary slightly with age.
- Sex: Men tend to have slightly higher ALT levels than women.
- Medications: Certain medications can elevate ALT levels.
- Underlying Health Conditions: Liver diseases, obesity, and diabetes can impact ALT levels.
- Muscle Injury: Strenuous exercise can cause a temporary elevation in ALT.
When to Consult a Doctor
It's important to consult a healthcare professional if your ALT levels are consistently outside the normal range. A doctor can help determine the underlying cause and recommend appropriate treatment or lifestyle changes.
Examples
- An ALT level of 30 U/L generally indicates a healthy liver.
- An ALT level of 80 U/L might suggest mild liver inflammation or damage.
- An ALT level above 400 U/L often indicates significant liver damage.
