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.
ALT Liver Test, elevated information, measures liver damage and health problems, natural ways to reduce levels by Ray Sahelian, M.D. An initial step in detecting liver damage is a simple blood test to determine the presence of certain liver enzymes in the blood. Under normal circumstances, these enzymes reside within the cells of the liver. But when the liver is injured, these enzymes are spilled into the blood stream. Among the most sensitive and widely used of these liver enzymes are the aminotransferases. They include GGT, aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT). These enzymes are normally contained within liver cells. If the liver is injured, the liver cells spill the enzymes into blood, raising the enzyme levels in the blood and signaling the liver damage.
