A pregnancy test detects human pregnancy hormone human chorionic gonadotropin hCG to determine whether an individual is pregnant. HCG testing can be performed on a blood sample typically done in a medical office or hospital or on urine which can be performed in an office, hospital or at home.
Identified in the early 20th century, hCG rises quickly in the first few weeks of pregnancy, peaking at 10 weeks. Urine tests will typically show positive around four weeks after the last menstrual period LMP and are best done in the morning as hCG levels are then highest. Obstetric ultrasonography may also be used to detect pregnancy.
The order of detection from earliest to latest is that hCG can be detected earliest in the blood, then a urine test, then ultrasound. Chemical tests for pregnancy look for the presence of the beta subunit of human chorionic gonadotropin hCG in the blood or urine.
With obstetric ultrasonography the gestational sac sometimes can be visualized as early as four and a half weeks of gestation approximately two and a half weeks after ovulation and the yolk sac at about five weeks' gestation. The embryo can be observed and measured by about five and a half weeks.
The heartbeat may be seen as early as six weeks, and is usually visible by seven weeks' gestation. Although all current pregnancy tests detect the presence of beta hCG, research has identified at least one other possible marker that may appear earlier and exclusively during pregnancy.
For example, early pregnancy factor EPF can be detected in blood within 48 hours of fertilizationrather than after implantation. Improper usage may cause both false negatives and false positives. False negative readings can occur when testing is done too early. Menstruation occurs on average 14 days after ovulation, so the likelihood of a false negative is low once a menstrual period is late.
Ovulation may not occur at a predictable time in the menstrual cyclehowever. A number of factors may cause an unexpectedly early or late ovulation, even for women with a history of regular menstrual cycles. It is normal for sperm to live up to five days in the fallopian tubeswaiting for ovulation to occur. Urine tests can be falsely positive in those that are taking the medications: chlorpromazinephenothiazines and methadone among others.
Spurious evaporation lines may appear on many home pregnancy tests if read after the suggested 3—5 minute window or reaction Aim stick pregnancy test, independent of an actual pregnancy. False positives may also appear on tests used past their expiration date. A woman who has been given an hCG injection as part of infertility treatment will test positive on pregnancy tests that assay hCG, regardless of her actual pregnancy status.
However, some infertility drugs e. Some diseases of the livercancersand other medical conditions may produce elevated hCG and thus cause a false positive pregnancy test.
Pregnancy tests may be used to determine the viability of a pregnancy. Serial quantitative blood tests may be done, usually 3—4 days apart. Failure to increase normally may indicate an increased risk of miscarriage or a possible ectopic pregnancy.
Ultrasound is also a common tool for determining viability. A lower than expected heart rate or missed development milestones may indicate a problem with the pregnancy.
Inaccurate estimations of fetal age and inaccuracies inherent in ultrasonic examination may cause a scan to be interpreted negatively. Records of attempts at pregnancy testing have been found Aim stick pregnancy test far back as the ancient Greek and ancient Egyptian cultures. The ancient Egyptians watered bags of wheat and barley with the urine of a possibly pregnant woman. Germination indicated pregnancy.
The type of grain that sprouted was taken as an indicator of the fetus's sex. Hippocrates suggested that a woman who had missed her period should drink a solution of honey in water at bedtime: resulting abdominal distention and cramps would indicate the presence of a pregnancy. Avicenna and many physicians after him in the Middle Ages performed uroscopya nonscientific method to evaluate urine. Selmar Aschheim and Bernhard Zondek introduced testing based on the presence of human chorionic gonadotropin hCG in In the s, Doctor Georgeanna Jones discovered that hCG Aim stick pregnancy test produced not by the pituitary gland, but by the placenta.
This discovery was important in relying on hCG as an early marker of pregnancy. Presence of ovulation indicated that the urine contained hCG and meant that the person was pregnant. A similar test was developed using immature rabbits. Here, too, killing the animal to check her ovaries was necessary. At the beginning of the s, Hillel Shapiro and Harry Zwarenstein, who were researchers at the University of Cape Towndiscovered that if urine from a pregnant female was injected into the South African Xenopus toad and the toad ovulated, this Aim stick pregnancy test that the woman was pregnant.
This test was used throughout the world from the s to s, with Xenopus toads being exported live in great numbers. A later article, independently authored, granted Hogben credit for the principle of using Xenopus to determine gonadotropin levels in pregnant women's urine, but not for its usage as a functional pregnancy test.
Hormonal pregnancy tests such as Primodos and Duogynon were used in the s and s in the UK and Germany. These tests involved taking a dosed amount of hormones, and observing the response a few days later. A pregnant woman does not react, as she is Jesse waller the hormones in pregnancy; a woman not pregnant responds to the absence of the hormone by beginning a new menstrual cycle.
While the test was is generally considered accurate, research advancements have replaced it with simpler techniques. Immunologic pregnancy tests were introduced in when Wide and Gemzell presented a test based on in-vitro hemagglutination inhibition. This was a first step away from in-vivo pregnancy testing   and initiated a series of improvements in pregnancy testing Aim stick pregnancy test to the contemporary at-home testing.
Organon International obtained the first patent on a home pregnancy test intwo years after product designer Margaret Crane noticed that the laboratory testing procedure was relatively simple and made Granny goose green onion prototype.
Another home pregnancy testing kit was based on the work of Judith Vaitukaitis and Glenn Braunstein, who developed a sensitive hCG assay at the National Institutes of Health. Tests are now so cheap that they can be mass-produced in a general publication and used for advertising.
