What are considered high levels of AST and ALT?

Typically the range for normal AST is reported between 10 to 40 units per liter and ALT between 7 to 56 units per liter. Mild elevations are generally considered to be 2-3 times higher than the normal range. In some conditions, these enzymes can be severely elevated, in the 1000s range.

What is the reference range for TSH?

TSH normal values are 0.5 to 5.0 mIU/L. Pregnancy, a history of thyroid cancer, history of pituitary gland disease, and older age are some situations when TSH is optimally maintained in different range as guided by an endocrinologist. FT4 normal values are 0.7 to 1.9ng/dL.

Can hypothyroidism cause elevated ALT levels?

Also, researchers found that 20.1% of patients with subclinical hypothyroidism and 25.9% of patient with overt hypothyroidism had abnormal ALT (p<0.001).

What is a good AST ALT ratio?

A normal AST:ALT ratio should be <1. In patients with alcoholic liver disease, the AST:ALT ratio is >1 in 92% of patients, and >2 in 70%. AST:ALT scores >2 are, therefore, strongly suggestive of alcoholic liver disease and scores <1 more suggestive of NAFLD/NASH.

When should I worry about Alt?

Any elevation of the ALT is a direct indication of a liver injury, whether minor or severe. Occasional increases may occur in association with a short-term infection or illness. Sustained increases are more problematic as they suggest an underlying disease and a greater likelihood of liver damage.

Can hypothyroidism affect liver function?

Serum liver enzyme abnormalities observed in hypothyroidism may be related to impaired lipid metabolism, hepatic steatosis or hypothyroidism-induced myopathy. Severe hypothyroidism may have biochemical and clinical features, such as hyperammonemia and ascites, mimicking those of liver failure.

Why would ALT be elevated but not AST?

While increased AST levels are indicative of a tissue injury, it is not specific to the liver per se. By contrast, alanine aminotransferase (ALT) is found primarily in the liver. Any elevation of the ALT is a direct indication of a liver injury, whether minor or severe.

What is the normal level of AST in blood?

Values are typically at least 10 times above the normal range. Levels may reach values as high as 100 times the upper reference limit, although 20- to 50-fold elevations are most frequently encountered.

What do high ( elevated ) liver tests ( AST and Alt ) mean?

What do high (elevated) liver tests (AST and ALT) mean? AST (SGOT) and ALT (SGPT) are reasonably sensitive indicators of liver damage or injury from different types of diseases or conditions, and collectively they are termed liver tests or liver blood tests.

How to find out your AST and ALT ratio?

Here’s an easy way to find out your AST:ALT ratio: divide your AST level as shown on your blood test results by your ALT level. For example, if your AST is 20 U/L and your ALT is 18 U/L, then your ALT ratio would be 1.05, which is within the normal range. What is the magnitude of AST and ALT elevations for acute viral hepatitis?

What’s the normal reference range for serum TSH?

Subsequent findings confirmed that ethnicity, iodine intake, gender, age, and body mass index can influence the reference range of serum TSH. In fact, the normal TSH upper limit was lower in African Americans (3.6 mIU/L) than in Mexican Americans or Caucasians (4.2 mIU/L) ( 8 ).
