My friend who has been diagnosed with Covid19 15 days back, has undergone blood test 2 days ago in which some values are abnormal. SGOT- 112.2, SGPT- 263 U/L, LDH- 354, Ferritin - 982.3. D dimer was also high but after clexane injection value is fine now. He is non alcoholic, non smoker. He has 17 mm stone in his gall bladder. Kindly suggest the possible reason for the high values and whether it is serious or not.
