The pregnancy test is also accurate if tested at night. Due to the technical improvement of the pregnancy test, then it is more sensitive to the HCG in the urine, so the pregnancy test is now accurate whether tested in the morning or at night. However, if you have just stopped menstruating, it is recommended to take the test in the morning if the HCG value in the urine is not high. This is because the HCG in the morning urine will be relatively high. In addition, the following points should be noted before the urine test. First, do not drink too much water to avoid dilution of the urine, so that the HCG value will be lowered and the pregnancy test will not detect it, and a false negative will occur. In addition, when collecting urine, make sure to find a clean cup, not a medicine bottle, so that the drug does not remain in it and affect the test results.
