Beckman Coulter Access Free T3, Triiodothyronine, Free, Catalog #A13422, each box contains 2 reagent packs.

Reason: The reagent lot produces elevated results (approximately >30%) in some (15-20%)patient samples that do not correlate with the results of other thyroid markers nor Free T3 results generated on other platforms. This introduces a risk of the positive bias not being detected by QC with the potential that clinical correlation with other thyroid function tests will be inconsistent requiring additional testing; however the clinical assessment and treatment decisions are not made in isolation on a single test result especially, in the setting of thyroid function testing. False positive test results could lead to a euthyroid patient being interpreted clinically as having elevated thyroid function (hyperthyroid) or a hypothyroid patient being within the normal range. Such misdiagnoses may lead to inappropriate treatment of a euthyroid patient with anti-thyroid medications or hypothyroid patient not getting sufficient treatment since their free T3 test result demonstrates them to be in the euthyroid range.
