Lactic dehydrogenase (LDH) values refer to total serum LDH. Total LDH levels are elevated at some time in 92%-95% (literature range, 82%-100%) of patients with acute MI. Statistics for sensitivity in acute MI refer to multiple sequential LDH specimens and are therefore not valid for any single determination. In acute MI, LDH becomes elevated 24-48 […]
Lactic dehydrogenase (LDH) is found in heart, skeletal muscle, and RBCs, with lesser quantities in lung, lymphoid tissue, liver, and kidney. A considerable number of conditions can elevate total LDH levels. For that reason, serum total LDH has not been very helpful as a liver function test. However, in some cases isoenzyme fractionation by electrophoresis […]
Certain laboratory tests are extremely helpful in suggesting or demonstrating the presence of hemolytic anemia. Which tests give abnormal results, and to what degree, depends on the severity of the hemolytic process and possibly on its duration. Reticulocyte count. Reticulocyte counts are nearly always elevated in moderate or severe active hemolytic anemia, with the degree […]
