Why is It Better to Take Pregnancy Test in Morning

Pregnancy tests are both laboratory tests and tests now conducted at home to confirm conception and pregnancy. These can be conducted using both blood samples or samples of urine. Earlier these could only be conducted in the laboratory. Today these tests can be conducted I the confines of a home too. Several pregnancy home test kits are available in the market. These kits are easy to use. These home test kits use a urine sample to confirm pregnancy. It is however still advisable to seek further confirmatory tests after reporting to a practitioner even after a confirmation through a home pregnancy test kit. These are advised since it is imperative to check if the pregnancy is viable and to avoid chances of an ectopic pregnancy. The practitioner can conduct an ultra-sonography to confirm the presence of a gestational sac in the uterus and can confirm the implantation in the uterus.

Most of the pregnancy tests check for the presence of the pregnancy hormone in the blood or urine sample. The pregnancy hormone called as the human chorionic gonadotropin or hCG can be detected in the blood and urine sample after implantation of the embryo. This implantation usually occurs 6 to 12 days after fertilization. However most of the home pregnancy tests are based on a technology called the lateral flow technology. Improper usage of the home test kit could result in both false positives and false negatives. This is another reason why these home test kits must be followed by a visit to the practitioner and further confirmatory tests conducted.

It is usually the first morning urine sample that is recommended for most pregnancy tests. This is the reason why take a pregnancy test in the morning. The reason behind taking an early morning sample is that this sample typically contains the highest concentration of the pregnancy hormone that is the human chorionic gonadotropin hormone or hCG . However this is not a strict instruction. This urine sample which is high in the pregnancy hormone concentration can be re- created. This can be done if one holds back the urge to urinate for at least a period of four hours. What also needs to be kept in mind is that one must not consume excessive quantities of fluids during this duration. This is done to avoid diluting the urine sample. A home test conducted in the fourth or fifth week usually gives correct results without even the need to use the early morning urine sample. This is so because at this stage the levels of hCG are high enough.
