When pregnant, the body starts producing a hormone known as human chorionic gonadotropin (hCG). Whether you’re taking an at-home pregnancy test, or are going in for a clinical blood test, this is the hormone that is being tested for. If it’s detected, it’s indicative of pregnancy.  While many at-home pregnancy tests are capable of detecting hCG at any time following the expected date of your period, it’s common to get a false negative within the first few days. Therefore, most medical professionals recommend taking an at-home test one week following your missed period for the most accurate results.  In contrast, clinical blood testing can provide you with an accurate result within 1-2 days of your missed period.  Missing a period can be stressful, especially if you don’t know the cause. At The OB-Gyn & Incontinence Center, we provide safe and professional testing to get you the answers you need on time. For more information contact us or book an appointment online.
