What Are Flashing Lights? When flashing lights occur you may think that you see lights going on and off, especially to one side. These tend to happen in only one eye at a time, even when your eye is closed. What Causes Flashing Lights? The vitreous sometimes pulls on the retina. This may cause you to see flashing lights or lightning streaks, even though there aren't any such lights present. This is the same thing that occurs when you get hit in the eye and see stars or when you rub your eye.
Best Answer: HEPATIC (LIVER) ENZYME VALUES. AST (Serum Glutamic-Oxalocetic Transaminase - SGOT ) - found primarily in the liver, heart, kidney, pancreas, and muscles. Seen in tissue damage, especially heart and liver. Normal Adult Range: 0 - 42 U/L. Optimal Adult Reading: 21. ALT (Serum Glutamic-Pyruvic Transaminase - SGPT) - Decreased SGPT in combination with increased cholesterol levels is seen in cases of a congested liver.
The liver is responsible for detoxifying substances such as alcohol and drugs in your body, storing certain vitamins and minerals, such as iron and vitamin A, and storing glucose to be available as fuel. So what causes high liver enzyme levels to show up in a liver-function blood test? Alanine transaminase, or ALT, and aspartate transaminase, or AST, are the two most common liver enzymes to be tested. It is relatively common for one or both of these liver enzymes to be high. These enzymes leak out into the blood when liver cells are damaged or destroyed, the Mayo Clinic explains.
