My beta-hCG level was 17,169 three months back, and now it is 27,524. Why?

Hello.

Welcome to icliniq.com.

I understand your concern and will help you regarding it. The negative hCG (human chorionic gonadotropin) test is less than 5 mIU/mL. A urine pregnancy test can detect 20 to 50 mIU/mL of hCG. The levels you have mentioned are not normal by any means. An elevated beta-hCG in the absence of pregnancy can occur for many other causes and has a diverse differential diagnosis including but not limited to miscarriage, an ectopic pregnancy, pituitary hCG production, trophoblastic diseases, and phantom hCG. Ectopic pregnancy is frequently suspected when beta-hCG levels fail to double within 48 hours without ultrasound evidence of intrauterine pregnancy. Few other but uncommon causes of false-positive hCG are heterophile antibodies and certain malignancies. I hope this was helpful. Please get back if you have further doubts.
