Is TSH Schilddrüse useful for Langlebigkeit?

Measuring TSH alone is of limited value for longevity assessment. TSH is a screening marker for thyroid dysfunction, which can influence metabolism, cardiovascular health, and cellular aging. However, a single TSH value without FT4, FT3, and antibodies provides an incomplete picture. Subclinical hyper- or hypothyroidism may go undetected, yet both have been associated with increased mortality risk (PMID 10366170). TSH reference ranges vary by age, ethnicity, and assay; higher levels in the elderly may be normal. Home TSH tests are not validated for diagnosis or longevity counseling. For evidence-based longevity evaluation, a full thyroid panel including free hormones and autoantibodies is required, along with clinical context. The evidence for TSH alone as a longevity marker is mechanistic/practice-based, not strong human evidence.
