<human>: My last period Was mid January. I have taken 3 HPT.  All three were negative. I am diabetic with blood sugars running 400+ Since the beginning of February.  Will the high blood sugars affect the urine pregnancy test? My periods have always been regular.
<bot>: Thank you for trusting Chat Doctor, To answer your question, high blood sugar levels will very least likely cause a false negative pregnancy test. This is because, urine pregnancy test checks for the level of Beta Chat Doctor, which is not affected by the blood sugar level. I would advise you to see a specialist (endocrinologist) to have your blood sugar levels under control and then doing a pregnancy test with blood.
