How Long After Having HCG Injection Can I Confirm Pregnancy?

Posted on Fri, 3 Jul 2015

Question: Yesterday, seven days after my ovulation, I did a blood test and my level of hcg was 6.7 iu/L. The labo says it's positive because It's really early in pregnancy.

I want to do another blood test to confirm my pregnancy. if I do it tomorrow morning, is it supposed to answer this question ?

I just want to specify that I had an hcg injection on XXXXXXX 2nd (10 000 iu) and a blood test made six days after that was 21,3 iu/L.

Just want t make sure that my result (6.7 iu/L) 9 days after the injection is a real result and I want to know if another blood test tomorrow, so 48 hours after de last one, would confirm my pregnancy !

Thank you very much :)

Brief Answer:
Repeat after one week

Detailed Answer:
Hi,

Your previous hCG injection has no effect on hCG value as it was more than one week back.

You are in early pregnancy as per these values.

Repeating after 48 hours may not give exact double value as it is early pregnancy. Please repeat the beta hCG after one week.
