| Summary: | Persistent elevation of thyroid stimulating hormone (TSH) is a common clinical problem in outpatient clinics treating patients with primary hypothyroidism. One challenge to practitioners involves predicaments where patients have an inadequate response to a seemingly appropriate dose of levothyroxine (L-T4). A patient’s self-assessed compliance to hormone replacement therapy or verification refill history at the patient’s pharmacy might not be a reliable form of confirmation of non-adherence to the drug by the patient, which has been referred to as “L-T4 pseudo-malabsorption.” A fast and inexpensive tool to rule out true LT4 malabsorption and thereby properly diagnosing and ultimately successfully treat LT4 pseudo-malabsorption is available in the outpatient setting. This allows clinicians to identify which patients for individual support in adhering to their prescribed therapy and may also reduce unnecessary referrals for sub-specialty care by endocrinologists. |
