BioTest Pregnancy Test Kit detects the hCG (human chorionic gonadotropin) hormone in the urine that your body produces during pregnancy. You can test as early as the first day you miss your period. The test can be done anytime of the day; but your first morning urine specimen is usually the most concentrated of the day and would have the most hCG hormones in it. BioTest Pregnancy Test Kit is CE marked meeting the highest European standard, MDA approved and won many awards from Best Pregnancy Test to Most Wanted Pregnancy Test around the region. BioTest Pregnancy Midstream Test is the most convenient format. It has an elongated plastic casing with a cover. Once you open the cover, you can place the test directly under your urine stream, close the cover and wait for the result.
