Overview

Total Testosterone (Blood Spot) measures testosterone using a dried blood sample collected from a fingertip. Blood spot collection reflects hormone levels in capillary blood and correlates well with serum measurements for endogenous testosterone.

Practitioners may consider this assessment when clients report concerns such as low energy, mood changes, reduced libido, sleep disturbances, slower recovery or changes in body composition. Exploring testosterone levels alongside these concerns can help clarify broader hormonal patterns.

Results are typically reviewed alongside symptom history, stress exposure, sleep patterns, physical activity, dietary intake and any supplement or medication use. This supports a more complete understanding of how testosterone patterns may relate to energy, mood, physical comfort and general wellbeing for clients.
