Dehydration leads to concentrated and less urine production which in turn might contain high concentration of hCG. 6,7 So, if very high levels of hCG are suspected, the test should then be repeated with the diluted specimen, 1 in 10 or 100.

Is dark yellow urine a sign of pregnancy?

Does drinking water affect hCG levels?
It’s called a quantitative hCG blood test because it can measure exactly how much hCG is in your blood. In this case, the amount of water that you drink will not affect the results, as it will not alter the level of hCG in your blood, even very early in pregnancy.
How can I tell if my hCG levels are rising?
The levels of hCG rise rapidly in the earliest days of pregnancy and can be detected around eight days after the estimated day of conception in the blood by the most sensitive laboratory methods. Home pregnancy tests can detect it a few days later in urine depending on their sensitivity.
How can I check my hCG levels at home?
For some home pregnancy tests, you’ll hold an indicator stick directly in your urine stream until it’s soaked, which should take about 5 seconds. Other kits require that you collect urine in a cup and then dip the indicator stick into the cup to measure the hCG hormone level.
