Healthy 54 yo woman sched 4 acdf c5-6. blood low 6.8 mpv & high 42 ptt. prothromb w/inr: inr 1.0 ratio; prothromb 10.7 secs. will this delay surgery?

Anemic: If ones hemoglobin is 6.8, that represents marked anemia. It merits an evaluation prior to surgery. The PTT is at upper normal range.

Depends on surgeon: I would probably not delay your surgery for a mildly elevated PTT unless there were family history of bleeding problems, or history of abnormal bleeding (bloody noses, very heavy menstrual cycles, unusual bleeding in previous surgery). Your inr is normal. The risk of abnormal bleeding is quite low.

Probably not: Such a surgery is associated with very minor blood loss in the hands of a well qualified surgeon. If your doctor performing the medical clearance is concerned, it could be delayed. From a surgical standpoint, it does not appear that it should delay such a surgery.
