Investors generally consider a business' debt ratio an indication of the stability of the business and whether its stock is a suitable investment. Often referred to as the debt-to-equity ratio, this ratio measures the amount of debt a company takes on to finance its operations vs. its amount of available capital.
A lactate dehydrogenase (LD or LDH) test is a non-specific test that may be used in the evaluation of a number of diseases and conditions. LD is an enzyme that is found in almost all of the body's cells (as well as in bacteria) and is released from cells into the fluid portion of blood (serum or plasma) when cells are damaged or destroyed.
You may also have a lactate dehydrogenase isoenzyme test. Your total LDH is made up of 5 isoenzymes numbered LDH-1 through LDH-5. The concentration of each isoenzyme depends on the tissue.For example, LDH-1 and LDH-2 are found mainly in heart tissue. LDH-5 is found mostly in the liver.A higher than normal total LDH means possible tissue damage. Your healthcare provider might order a lactate dehydrogenase isoenzyme test to find out which tissue is damaged or diseased.or example, LDH-1 and LDH-2 are found mainly in heart tissue.
