My father had Trop T test in June the value came under 5 and today also my father had Trop T due to chest pain the value come as 7.97 both the time it is under normal range. But why fluctuation in reading ? Also the chest started early morning around 4 am and Trop was done after 10 hours at 2 PM. So whether the trop T can still increase or it might have reached its peak ? Along With Trop T CK mb was done which was normal too.
