This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Enzyme uses, Subject name: Biochemistry
Which of the following flipped pattern of LDH is seen in myocardial infarction: 
Select and explain. 
A. LDH 1>2, B. LDH 2> 1, C. LDH 3>4, D. LDH 5> 4
A: LDH 1>2
Answer: A: LDH 1>2 
Explanation: In normal person, LDH-2 is more than LDH-1 in serum. BUT in myocardial infarction, LDH-1>>LDH-2. This is known as Flipped ratio of LDH in Myocardial Infarction. ADDITIONAL EDGE ON ISOENZYMES OF LDH: LDH-2 is raised in haemolytic anemia. (LDH-2 is mainly found in blood (Both WBC and RBC; WBC conc. > RBC conc.)
