NG PRECISION+ Pregnancy Blood Test can detect even a small level of hCG in your blood (the test sensitivity is 10mlU/mL) with more than 99% accuracy. You can take the test anywhere and at any time of the day or night as you don’t need to wait for a first morning urine. HCG, or the pregnancy hormone, is a hormone produced by the placenta during pregnancy. HCG starts to be produced around 6 days after fertilisation and it appears in blood first, before it appears in urine (up to 3 days sooner). This is why hCG blood tests are the method of choice for laboratory testing, and what makes NG PRECISION+ superior to traditional urine testing. Boasting a revolutionary all-in-one device, the NG PRECISION+ test also simplifies the testing process by integrating the steps into one single device. Using just a small drop of blood the device is quick and simple to use. Not only that, but there’s no need to take a urine sample either. Hygienic as well as simple to use.
