Rapid thyroid test kits that screen for raised TSH in fingerstick blood or serum, in cassette and strip formats, for outreach programmes, clinics, pharmacy chains and IVD distributors.

Product Description:

Rapid thyroid tests are lateral flow immunoassays for thyroid-stimulating hormone (TSH), the pituitary hormone that rises when the thyroid is underactive. A sandwich assay on the strip gives a coloured line when TSH in a fingerstick blood or serum sample is above a set cut-off, so the result is qualitative or semi-quantitative rather than a laboratory value. Formats include cassettes with dropper and buffer and point-of-care test strips.

Their role is screening for possible hypothyroidism where a laboratory is out of reach, for example in outreach, workplace or pharmacy programmes. A positive screen needs a quantitative laboratory TSH and free T4 before any diagnosis or treatment. A negative screen does not rule out thyroid disease, and a cut-off test for raised TSH is not designed to detect an overactive thyroid. TSH also shifts with acute illness and some medicines. Newborn screening for congenital hypothyroidism uses dried blood spots tested in the laboratory, not these cassettes.

Sourcing notes. TSH rapid tests are in vitro diagnostics; check whether the destination market registers them for professional use only or also for self-testing. Ask for the instructions for use stating the cut-off and how it was set, comparison data against a laboratory TSH method, the ISO 13485 certificate and lot release records. Most kits are stored at room temperature within a labelled range, so protect them from heat in transit and keep the foil pouch sealed until use. Specify sample type, format, tests per kit and expected volume.
