LDH

אנזים הנמצא ברקמות שונות. נזק ברקמות שונות- לדוגמא נזק לכדוריות אדומות בזמן לקיחת דם לא נכונה יכול להעלות אותו- מי שלוקח את הדם יכול לדעת או עם רשום המוליטי- אז אין לתשובה ערך. כפי המופיע בקטע למטה יכול לעלות בזמן מחלות זהומיות בזמן מחלות באברים שוניםכמו: כבד, ריאות, לבלב כליה, מעי ועוד.... The enzyme LDH is found in many body tissues like the heart, liver, kidney, skeletal muscle, brain, blood cells, and lungs. LDH is very important for metabolism. LDH exists in 5 forms -- isoenzymes, which differ slightly in structure. LDH-1 is found primarily in heart muscle and red blood cells. LDH-2 is concentrated in white blood cells. LDH-3 is highest in the lung. LDH-4 is highest in the kidney, placenta, and pancreas. LDH-5 is highest in the liver and skeletal muscle. All of these isoenzymes can be measured in the blood. What abnormal results mean Because LDH can be found in many tissues in the body, total LDH is not specific for heart disease. Normally, the concentration of LDH-2 is greater than LDH-1. However, after a heart attack, the concentration of LDH-1 is generally higher than that of LDH-2. (This is called a "flipped" LDH pattern.) The serum LDH level rises within 24 to 72 hours after a heart attack, peaks in 3 to 4 days, and returns to normal in about 14 days. Greater-than-normal LDH isoenzyme levels may be seen in: Heart attack Hemolytic anemia Hypotension Infectious mononucleosis Intestinal ischemia (blood deficiency) and infarction (tissue death) Liver disease (e.g., hepatitis) Muscle injury Muscular dystrophy Pancreatitis Pulmonary (lung) infarction (tissue death) Stroke Ischemic cardiomyopathy is an additional conditions under which the test may be performed. Drugs that can increase LDH measurements include anesthetics, aspirin, clofibrate, fluorides, mithramycin, narcotics, and procainamide.
