My wife has a miscarriage on Sept, 30 2014, Dr. has suggested for APTT using Cephaloplastin reagent. Result: Control : 24 sec Normal Range: 21-29 sec Test sample (my wife sample): 31 sec Dr. said that this might be a reason for miscarriage? My question is is it a severe problem? What is the treatment? It may repeat next time when she is pregnant? Some people say its better to have six months gap and recent research says its better to conceive with in six months, so that there wont be complications. Now wife missed date on Nov 30, 2014. today we checked using Velocit (Pregnancy confirmation test) and its positive. Just let me know we need to continue this or stop it this carriage.
