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.
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.
