Your TSH was 2.1 last year and 4.8 this time…
Thyroid panels often include TSH, and sometimes free T4, free T3, and antibodies. Values shift with medications, pregnancy, other health changes, or simply over the course of care.
Without a timeline, comparing this year's TSH to last year's means digging through folders. MedLens+ places each result in chronological context so the shift is obvious at a glance.
Ranges that match your lab
TSH reference ranges vary between laboratories. We use the range printed on each uploaded report when flagging values, and warn when you're comparing results from different labs.
A flagged TSH is a signal to discuss with your clinician — not a label like hypothyroidism or hyperthyroidism.
Prep for endocrinology and primary care visits
Before your appointment, review your thyroid timeline and export a brief noting what changed since your last visit. Bring questions, not conclusions: "My TSH rose after the lab switch — should we retest?"
We never recommend levothyroxine dose changes or other treatment adjustments. Medication decisions are exclusively between you and your healthcare provider.
