<human>: Hi there doctor, I was taking the antibiotics Doryx until yesterday for 9 days because of a skin infection with boils due to a bad heat rash. Yesterday I did blood tests and this is what came out bad: Cholesterol total 218, high; LDL Cholesterol Calc 116, high; TSH 5.370, high; WBC Esterase Trace Abnormal; WBC 6-10 Abnormal. Could it be that the WBC is high because of the infection that I had? And if not, what would you recommend? And what would you recommend for the thyroid? Could the infection or antibiotics be affecting my thyroid? What is your general impression? Thanks a lot, I am a bit worried. Y.A.
<bot>: HI, thanks for using Chat Doctor Infections can cause a temporary increase in TSH and are also associated with an increase in WBC. Since you only completed the course of antibiotics the day before the bloods were taken, you should consider repeating them in 10 days to 2 weeks if you remain well. At that point the results can be taken as a true reflection of any issues that may be occurring. I hope this helps
