Between 10-11 and 14-15 weeks of pregnancy, a double and a triple screenings are performed respectively. It allows detecting any abnormalities in the fetal development.
By 6 to 7 weeks beta h CG levels may take as long as 3 1/2 days to double .
al., Symptomatic patients with an early viable intrauterine pregnancy: HCG curves redefined.
During pregnancy, your body produces a hormone called human Chorionic Gonadotropin (h CG).
h CG is produced by the cells that will form the placenta.
Throughout the pregnancy the expectant mother makes a great number of tests that help to track the normal fetal development or detect any abnormalities and fix them in a timely manner.
The woman takes a blood or urine tests to measure HCG levels (the blood test is considered more precise comparing to the urine test).
Enter the date the first blood test was drawn and the beta HCG value for the date the sample was drawn 2. Doubling times of human chorionic gonadotropin increase in early viable intrauterine pregnancies.
Enter the date the second blood test was drawn and the beta HCG value for the date the sample was drawn.
Most women can expect their levels to return to a non-pregnant range about 4 – 6 weeks after a pregnancy loss has occurred.
