Experiencing Symptoms: If you face fatigue, sudden weight gain or loss, mood fluctuations, or temperature sensitivity, it could indicate a thyroid imbalance.

Doctor's Recommendation: If a healthcare professional advises checking your TSH levels for diagnosis, treatment monitoring, or other medical reasons.

Special Instructions: If you take supplements containing Biotin (Vitamin B7, Vitamin B8, vitamin H, or coenzyme R), wait at least 72 hours after your last dose before collecting your sample to avoid interference with the results.

High levels of TSH, which may suggest hypothyroidism, are associated with symptoms like fatigue, weight gain, cold intolerance, dry skin, constipation, muscle weakness, and depression.
