A Selenium blood test kit is an at-home blood testing kit that measures the level of selenium in your serum. It uses a simple finger-prick sample you collect yourself and return to our UKAS-accredited laboratory for analysis.
To test your selenium levels at home, order our Selenium Home Blood Test Kit. You’ll receive a TDL Tiny finger-prick collection kit, follow the instructions to take a small blood sample, then send it back for fast, reliable results.
Our at-home selenium blood tests use the same serum analysis techniques as clinical labs. Samples are processed in a UKAS-accredited facility to ensure accuracy matching in-clinic blood test kits.
Using the home blood testing kit is easy: wash your hands, use the lancet to obtain a finger-prick sample into the TDL Tiny tube, seal and label it, then post it back in the pre-paid envelope.
Low selenium levels can lead to weakened antioxidant defence, thyroid issues and impaired immunity. High levels may cause nausea or hair loss. Your detailed report will explain where your result falls in the optimal range and any next steps.
