The pregnancy test is not limited to the use of morning urine to do the test, only in the newly pregnant, because the HCG concentration in the urine in the morning will be relatively high, so this time to do the test using morning urine, the (+) rate of the results will be a little higher. As the pregnancy continues, the HCG concentration in the urine will gradually increase, so the (+) rate will be higher if the pregnancy is detected at around 40 days after menopause, no matter when the urine test is done. It is recommended that morning urine be used for the test if it is within 35 days of menopause, and care must be taken not to drink too much water within 2 hours before the urine specimen is taken, as a false (-) result may also occur if too much water is consumed resulting in dilution of the urine.
