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 Direct contributions to a Roth IRA (principal) may be withdrawn tax and penalty-free at any time. 2  Earnings may be withdrawn tax and penalty-free after 5 years if the condition of age 59Â½ (or other qualifying condition) is also met.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.
An alanine aminotransferase (ALT) test measures the level of ALT enzyme in your blood. ALT is an enzyme produced by liver cells. It helps the body metabolize proteins. If the liver is damaged or not functioning properly, ALT is released into the blood. This causes ALT levels to increase.
