Hi I just wondered if anyone could give any advise. My child (12) had bloods for some unexplained bruising. Every test you could think of was completed and all were normal apart from one stage prothrombin time (blood clotting screening test). It has come back above range at 14.7. This is only slightly above normal range as the limits are 9.7 to 13.7. I’m an incredibly anxious person and am now terrified something is seriously wrong. All I can find online are terrifying reasons why it could be high. Has anyone got any experience or any advise. I don’t want to call the doctors because they already get fed up of me. I just worry so much when it’s children. The test is being repeated in 3 weeks and was very dehydrated when the first test happened if that makes a difference. They also received a vaccine at school the same day so I didn’t know if that affects the results. I panic everything could be cancer and to be honest I’m totally drained from being worried all the time. Any help would be much appreciated l. Thanks.
