This is a question for your DR. Look at the information below. Personally I feel that those numbers are too low but then again this is a question for your OB or RE (Reproductive Endocrinologist)
The "normal" ranges for the Beta hCG blood pregnancy test are shown in the table below.
Week from the Last Menstrual Period
Amount of HCG in mIU/ml
3 - 426
19 - 7,340
1,080 - 56,500
7 - 8
7,650 - 229,000
9 - 12
25,700 - 288,000
13 - 16
13,300 - 254,000
17 - 24
4,060 - 165,400
25 - 40
3,640 - 117,000
Because of the wide variation in values, the test is not useful in establishing the gestational age of a pregnancy.
Beta hCG levels should double approximately every 2 days for the first four weeks of pregnancy . As pregnancy progresses the doubling time increases. By 6 to 7 weeks gestation beta hCG levels may take as long as 3 1/2 days to double [3,4].
You can use the Beta hCG Doubling Time Calculatorto calculate the doubling time of two beta hCG samples by entering the date of the blood test and the corresponding beta hCG value for that day. If the hCG level is declining the the half life of will be calculated.
