The Trinidad Immunoassay (IM) system is an automated, immunoassay analyzer designed to perform in vitro diagnostic tests on clinical specimens. The Trinidad IM system’s assay applications utilize chemiluminescent technology for clinical use.

The Trinidad IM Thyroid Stimulating Hormone (TSH) assay is for in vitro diagnostic use in the quantitative determination of thyroid-stimulating hormone (TSH, thyrotropin) in human serum and plasma (EDTA and lithium heparin) using the Trinidad IM system. Measurements of thyroid stimulating hormone produced by the anterior pituitary are used in the diagnosis of thyroid or pituitary disorders.

The Trinidad IM TSH Calibrators are for in vitro diagnostic use in calibrating the Trinidad IM system TSH assay.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
