Point-of-Care Urine Pregnancy Tests

Abstract

A 40-year-old woman with a history of Graves disease presented for evaluation of abdominal pain and constipation. She was evaluated 3 months earlier for 3 to 4 months of amenorrhea. At that time, a point-of-care (POC) urine human chorionic gonadotropin (hCG) test was negative for pregnancy. Thyroid-stimulating hormone was undetectable (Table ) and a subsequent radioiodine thyroid uptake study was consistent with Graves disease. She was prescribed methimazole but continued to have amenorrhea and reported abdominal fullness and constipation. Vital signs were unremarkable at the current presentation. Physical examination revealed a tender midline abdominal mass. Answer B. Perform a serum human chorionic gonadotropin (hCG) test.
