A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography. [1] Testing blood for hCG results in the earliest detection of pregnancy. [2]
During this method of prenatal testing, a sample of chorionic villi is removed from the placenta to be tested. This test is performed 10–13 weeks into pregnancy and results are ready 7–14 days after the test was done. [18] Another test using blood taken from the fetal umbilical cord is percutaneous umbilical cord blood sampling.
Blood and urine tests can detect pregnancy by 11 and 14 days, respectively, after fertilization. [78] [79] Blood pregnancy tests are more sensitive than urine tests (giving fewer false negatives). [80] Home pregnancy tests are urine tests, and normally detect a pregnancy 12 to 15 days after fertilization. [81]
In general, it's best to wait until you've missed your period, and to take the test first thing in the morning. Learn how timing impacts accuracy from experts.
A few days after the injection, the animal would be dissected and the size of her ovaries examined. The rabbit test became a widely used bioassay (animal-based test) to test for pregnancy.

Given everything she experienced last week, Lois’ attention is understandably divided on Tuesday’s Superman & Lois (The CW, 8/7c). TVLine’s exclusive sneak peek of the episode finds the ...
Human chorionic gonadotropin is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5kDa αhCG and 22.2kDa βhCG. [4]It is heterodimeric, with an α (alpha) subunit identical to that of luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and a β (beta) subunit that is unique to hCG.
The frog test had been a highly dependable pregnancy testing method since the 1930s until the immunological test was presented in the 1960s. [12] Pharmacists would inject the female's early urine sample into the frogs and confirm their pregnancy with the spawning of eggs within 18 hours. However, there was a critical prerequisite for accurately ...
