"In 1967, Margaret Crane was a 26-year-old product designer at Organon Pharmaceuticals, sketching face-cream bottles and ointment jars. One day, as she walked through a lab at the company’s headquarters in New Jersey, she spotted rows of test tubes on shiny racks that twinkled under the industrial lights. “What are these?” she asked one of the scientists. Pregnancy tests, he said. A doctor would collect urine from his patient and send it to the company’s lab for analysis. The results would be sent back to the doctor, who would then inform the patient. But Ms. Crane immediately saw another possibility: Why not cut out the doctor entirely?" Why at-home pregnancy tests weren't available until the late-seventies. (SLNYT)
Human chorionic gonadotropin (hCG) is a hormone produced during pregnancy and a marker in many pregnancy tests. After one man tested himself for pregnancy "for shits and giggles", his friend posted the surprising result in Rage Face form on Reddit... only to find out that elevated hCG levels in men are actually not lulzy (Reddit thread), resulting in an emergency visit to the doctor and a more thoughtful follow-up Rage Face comic.
