Brief Answer:

These are normal. No need to worry.

Detailed Answer:

Hello,

Thanks for posting your query.

I have seen all the attached reports. The raised levels of APTT and fibrinogen are normal during pregnancy. This does not indicate any clotting issues.

Pregnancy-induced hypercoagulability is probably a physiologically adaptive mechanism to prevent post partum hemorrhage.

Pregnancy changes the plasma levels of many clotting factors, such as fibrinogen, which can rise up to three times its normal value. Thrombin levels also increase during pregnancy.

I hope this answers your query.

Wishing you good health.

Regards,
