Your TSH result of 4.65 mIU/L at 12 pm (noon/afternoon) is likely a bit lower than if you had tested in the early morning. TSH follows a natural daily (circadian) rhythm: it peaks highest overnight/early morning (around 2-4 am, staying relatively high until ~8-9 am), then drops to its lowest in the late afternoon/evening. Testing at midday/afternoon can make TSH appear 10-30% lower (sometimes up to 1-2 mIU/L difference in some people) compared to an early morning sample. For most people, this variation is small and doesn’t change the overall interpretation (your value is still within or near normal range, usually 0.4-4.5 mIU/L). However, if you’re borderline (like monitoring subclinical hypothyroidism), the afternoon test might underestimate the true level slightly. The time of test does affect TSH, but usually not dramatically for routine checks.

Yes, the time of testing does affect TSH slightly. TSH is usually highest early morning and can be a bit lower by afternoon, but the difference is not huge. A value of 4.65 at 12 pm is still a valid result and not falsely low.
