When you’re pregnant, not only does your blood become more dilute (watered down), but the blood flow going through your kidneys increases up to 80 percent by 12 weeks of gestation. This can lead to more dilute urine, and our usual way of compensating for this (with urine creatinine levels) often isn’t enough.
Because of this, your Vessel test results can appear lower than they actually are. This usually isn’t a problem because in pregnancy you also have increased nutrient needs. However with some tests such as calcium, we don’t recommend relying on Vessel’s results.
