A member asked:

My 21 month old just had his coags done his pt and inr were normal but his ptt was 43 & 45 seconds ( we did it twice ). is this normal?

A doctor has provided 1 answer

Yes, nearly so.: Children often have longer PTT. As long as the child does not have abnormal bleeding, it is not worth pursuing lab values. Keep a watch for teeth related bleeding.
