AST ALT Test in Charleston, SC

What Is an AST ALT Test?

An AST ALT test measures two critical liver enzymes: aspartate aminotransferase (AST) and alanine aminotransferase (ALT). While ALT is highly specific to the liver, AST is also found in the heart, muscles, and other tissues. Checking both enzymes together provides more diagnostic information than either test alone.

Why Get an AST ALT Test in Charleston?

If you have elevated liver enzymes or symptoms of liver stress, comparing AST and ALT can help pinpoint the cause. The AST:ALT ratio is one of the most useful calculations in liver medicine:

• Ratio < 1 — typical of viral hepatitis and NAFLD
• Ratio > 2 — strongly suggests alcoholic liver disease
• Both elevated equally — may indicate drug toxicity or generalized inflammation

For Charleston residents, ordering both tests together saves time and gives your doctor more information to work with. Try our AST/ALT ratio calculator

How the AST ALT Test Works

The process is simple and takes about 10 minutes at the lab:

2. Choose a lab near Charleston — you'll receive a list of participating locations
3. Walk in for your blood draw — bring your requisition; appointments are usually not required
4. Get your results — both enzyme levels are reviewed and delivered securely online

Fasting is generally not required for an AST ALT test.

AST ALT Test Cost in South Carolina

In South Carolina, an AST ALT test typically costs between $35 and $70 when ordered online. A full liver function panel, which adds ALP, bilirubin, and albumin, costs slightly more but provides the most complete liver evaluation.

When Should You Get Both Enzymes Checked?

You should consider an AST ALT test if you:

• Have an elevated ALT and want to understand the cause
• Drink alcohol and are concerned about liver health
• Have recently engaged in intense exercise and want to rule out muscle injury
• Take medications that can affect the liver
• Have symptoms such as fatigue, jaundice, or abdominal discomfort
