This is thought differently.
Some doctors advise to prank soberly, while others advise not to do this. Make an appointment with your doctor.
If fasting is not fooled, the TSH value is slightly lower and the FT4 value is slightly higher than if it is foolishly pricked, here the interpretation of the values must be taken into account. With T4 usage only, the values do not fluctuate strongly throughout the day. If next T4 also T3 is swallowed, the fluctuations are stronger. It is advised to always prick at a fixed time.
