Tthyroid test results tsh 1.42 ft4 15 what do these results mean?

Is FT4 correct? Your TSH appears normal. Did you have a typp with the ft4, as a value of 15 is an order of magnitude too high. 1.5 would be normal. Another possibility is that the 15 is a T4 not a ft4. Either way, it's hard to tell but probably normal. Check w/your doctor.
