<s>[INST] Hi doctor, I was about to get a complete blood test done to check certain parameters. I have attached herein the screen shot of the parameters. I wanted to know if I have masturbated before 36 hours of these tests then would the results be adversely affected? If so, how many hours should lapse after I last masturbate to get these tests done? [/INST] Hi. For further information consult a family physician online --> </s>
