Tipsep-T4 Ria T4 Radioimmunoassay
Nuclear Diagnostics
FDA Clearance Information
The tipsep-t4 ria t4 radioimmunoassay was cleared by the FDA via the 510k pathway on January 16, 1980. It is manufactured by Nuclear Diagnostics and classified as a Class 2 device.
What It Is
FDA-Cleared Indications
- Measurement of thyroxine (T4) levels in human specimens by radioimmunoassay.
- Use in clinical laboratories as an aid in evaluating thyroid function.
Clinical Applications
- Laboratory measurement of T4 levels in patients being evaluated for thyroid dysfunction.
- Supportive testing in the assessment of suspected hypothyroidism.
- Supportive testing in the assessment of suspected hyperthyroidism.
- Monitoring thyroid hormone status when interpreted with clinical findings and other thyroid-function tests.

Practical Considerations
- This is an in-vitro laboratory assay rather than an implantable or invasive device.
- The assay requires appropriate patient specimens, laboratory reagents, controls, calibration, and radiation-safety procedures.
- Results should be interpreted with the laboratory's reference range and alongside clinical findings and other thyroid tests, such as TSH.
- Medication use, pregnancy, binding-protein abnormalities, and other illnesses may affect total T4 interpretation.
- MRI compatibility, vascular access, device sizing, and implant durability do not apply because the product is not implanted or placed in the body.
Frequently Asked Questions
What are the clinical indications for tipsep-t4 ria t4 radioimmunoassay?
The device is indicated for the measurement of thyroxine (T4) levels to aid in the diagnosis of thyroid disorders, as per FDA documentation.
What outcomes have been reported in clinical studies?
Studies have reported that the device provides sensitive and accurate T4 measurements, particularly in low concentration scenarios such as in fetal and neonatal subjects.
What complications have been reported?
Safety data indicate that iodinated contrast media can interfere with T4 measurements, potentially affecting the accuracy of the assay.
