I am 24 year male, my tsh level is 5.07 what cases of this?

Borderline: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, your TSH is higher than normal and suggest deficiency of thyroid hormone. It would be prudent to consult your doctor, preferably an endocrinologist, to initiate replacement treatment.
