Reference Interval for Pediatric PTs
> Thursday, September-18-2008From Colleen Marinucci at Elmendorf AFB in Alaska:
Our pediatrician uses "The Harriet Lane Handbook: A Manual for Pediatric House Officers" for coagulation reference ranges and said 10.6-11.4 seconds is an age specific range for the prothrombin time. Our adult range is 10.7-14.3. Her four-yo patient resulted twice at 14.6 seconds and has a history of epistaxis. She felt this abnormal result warrented a mixing study.
Any comments?
