To know whether pregnancy is present Urine Pregnancy Test is done using Urine Pregnancy Test Kit. One brand name that is popular in India is VELOCIT © manufactured and marketed by Dr. Reddy’s Laboratories.
In the past
to detect pregnancy women used to wait for missed period.
After an embroyo begins to grow, the menses cease. She does not get her period during her expected date.
In case pregnancy is suspected and not wanted as after unprotected sex the couple gets highly strung and immensely worried about the possibility of pregnancy.
Urine Pregnancy Test comes in handy to know whether Pregnancy is present.
How early can it detect presence or absence of pregnancy?
Can it give false results?
Urine Pregnancy Test can be done in secrecy.
DETECTING IN BLOOD
In normal pregnancy, hCG can be detected in serum as early as 7 days following
conception. The concentration of hCG continues to rise rapidly, frequently exceeding 100 mIU/ml by the first missed menstrual period and peaking in the
30-200,000 mIU/ml range by 10-12 weeks into pregnancy
How accurate is a urine pregnancy test?
Urine pregnancy test (UPT) kit is sensitive to detect 50 mIU/ml of hCG in urine.
(Some kits detect 25 mIU/ml).
One week before expected period hCG level in urine is between
5 to 50 mIU/ml.
Hence, practically urine pregnancy test can be relied upon not earlier than one week prior to expected date of next period. Commonly UPT is considered sensitive soon after missed period.
In case of doubt repeat the test 72 hours (3 days) later when the hCG further increases in urine. hCG levels double every 2 or 3 days.
VERY EARLY (IMMEDIATELY AFTER CONCEPTION)
The UPT certainly cannot detect pregnancy the day after sexual intercourse, meaning immediately on conception. It takes time for hCG level to rise enough to be able to be detected by urine pregnancy test kit.
For detecting earlier, blood levels of hCG may be done in Pathology Laboratory, which is equipped with the test. It is however not done commonly as it is expensive and does not have the secrecy and ease of doing test at home.
For ensuring that pregnancy should not happen immediately after intercourse
‘Emergency Contraception’ is legally and medically approved.
