A Roth IRA can be an individual retirement account containing investments in securities, usually common stocks and bonds, often through mutual funds (although other investments, including derivatives, notes, certificates of deposit, and real estate are possible). Direct contributions to a Roth IRA (principal) may be withdrawn tax and penalty-free at any time. 2  Earnings may be withdrawn tax and penalty-free after 5 years if the condition of age 59Â½ (or other qualifying condition) is also met.
How is it used? The blood test for aspartate aminotransferase (AST) is usually used to detect liver damage. It is often ordered in conjunction with another liver enzyme, alanine aminotransferase (ALT), or as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disorders.
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. However, it must be emphasized that higher-than-normal levels of these liver enzymes should not be automatically equated with liver disease.
