Normal hCG Levels

When a blood pregnancy test is run, the hCG level will be reported to the obstetrician. This level will give the doctor a look into the age and the health of the pregnancy. Normal hCG levels will vary based on the number of fetuses implanted in the uterus.

Normal hCG Levels for a Single Pregnancy

Each of the following levels are noted as being since the last menstrual period, often referred to as LMP on the hCG test results. For this reason, hCG levels provide only a guide that can be used in conjunction with other tests to determine the due date of the fetus. In order for hCG levels to be reported to the physician, a quantitative hCG test will need to be ordered. All values noted are in mlU/ml.

 Normal hCG Levels for a Multiple Pregnancy

The hCG levels for a multiple pregnancy tend to fall within the normal ranges of the twin pregnancy. The exception could be in the earlier weeks of gestation. If the quantitative blood hCG pregnancy test is run before the 10th week of pregnancy, the tests could report hCG levels at the higher limits of a single pregnancy or that the pregnancy is farther along than the doctor anticipated. This would lead to an ultrasound, which would confirm the multiple pregnancy. Not all obstetricians choose to run a quantitative hCG level before the 10th week, which can lead to the multiple pregnancy being discovered during other tests or the first ultrasound.
