Are AST and ALT completely useless for weight trainers?

[IronKnight]

Should people weight training completely ignore AST and ALT, and simply look at the other liver markers instead?

ALT & AST just seem unreliable for people doing weight training:

From one of the above:
What about GGT?

Unlike AST and ALT, GGT is not found in the muscle (although it is in other tissues). Elevated GGT cannot be attributed to muscle damage—unless the damage is so severe that other organs are being negatively affected. GGT is a more specific marker of overall liver health.

So, given my GGT is fine, as well as the other liver markers, are AST and ALT just nonsense markers that can be safely ignored?

AST and ALT are not completely useless in bodybuilding. They are part of the cheap CMP panel that also looks at kidney function and electrolytes. GGT is the way to go if you have high AST and ALT but it is more expensive and it takes a few days longer to get the results.

You may also say that about creatinine versus Cystatin C, by the way.

Is the Cystatin C Test Better than Creatinine for Muscular Men?

The cystatin C blood test is used to monitor kidney function in people experiencing or suspected to have kidney disease. If a physician suspects that you’re suffering from impaired kidney function the

CMP is a basic, cheap test that tells you a lot.

The comprehensive metabolic panel (CMP) is a blood test that measures several substances in your blood, including electrolytes, proteins, glucose, and liver and kidney function markers. It is often used to help diagnose and monitor a variety of medical conditions, such as diabetes, kidney disease, and liver disease. The test is usually done as part of a routine health evaluation or to check for potential health problems. The results of the CMP are usually reported as a series of numbers, with a reference range indicating the normal values for each substance measured. It is important to note that the interpretation of a comp metabolic panel may vary depending on the individual's medical history and other factors. A healthcare provider should be consulted to interpret the test results correctly. Tests included:

• Glucose
• Sodium
• Potassium
• Chloride
• Carbon Dioxide
• Calcium
• Protein
• Albumin
• Alanine transaminase (ALT)
• Aspartate transaminase (AST)
• Bilirubin
• Alkaline phosphatase (ALP)
• Blood urea nitrogen (BUN)
• Creatinine
• eGFR

The comp metabolic panel or CMP panel consists of 14 blood tests that are an initial medical screening tool to review overall health. The CMP blood test panel checks for kidney function, liver function, and electrolyte and fluid balance. FASTING IS REQUIRED. These are the tests included:
