The urine HcG values are usually lower than the blood (serum) HcG values. For example, if your serum HcG is 40 MIU/ml, which is normal for 15 DPO, then your urine HcG would be expected to be much lower. A urine pregnancy test with 25 mIU sensitivity would probably be negative even though you are pregnant. Here are the serum HcG values for singleton pregnancies: Average mIU/ml (high-low) 14 dpo: 48 119-17 15 dpo: 59 147-17 16 dpo: 95 223-33 17 dpo: 132 429-17 18:dpo: 292 758-70 19 dpo: 303 514-111 20 dpo: 522 1690-135 21 dpo: 1061 4130-324 22 dpo: 1287 3279-185 23 dpo: 2034 4660-506 24 dpo: 2637 10000-540 For more information about HcG, including a list of levels of HcG when expecting twins, please visit http://www.bobrow.net/kimberly/birth/hcglevels.html.
