False Positive Pregnancy Test Before Kidney Transplant: Case Report and Review of Literature

Abstract

Pregnancy tests are routinely done before any surgery under general anesthesia including kidney transplantation. Positive test usually leads to more investigations to detect a possible pregnancy or malignancy and the surgery gets canceled or postponed. Because a kidney transplant from a deceased donor is not elective, it usually gets canceled in this scenario. Some groups have reported on normally elevated human chorionic gonadotrophin (hCG) levels in perimenopausal women and in patients with chronic kidney disease. This is thought to be from the pituitary. We present a highly sensitized prospective kidney transplant recipient with a positive pregnancy test with low levels of serum human chorionic gonadotrophin. She underwent additional preoperative testing after which we proceeded with the kidney transplant. Herein, we discuss the management of patients who have an unexpected positive pregnancy test before transplant.
