T4 Test Kit

Introduction T4 Test Kit

The Total Thyroxine (T4) Test Kit is designed for the quantitative measurement of total T4 in human serum or plasma. Supplied in a 100-test format, the kit is specified as compatible with the CLIA PV 1800 analyzer.

The Total Thyroxine (T4) Test Kit is designed for the quantitative measurement of total T4 in human serum or plasma. Supplied in a 100-test format, the kit is specified as compatible with the CLIA PV 1800 analyzer. Total T4 measurement, when considered alongside TSH and other relevant tests, can support the assessment of thyroid function and the evaluation of conditions such as hypothyroidism and hyperthyroidism.

Clinical Applications of the Total T4 Test Kit

Thyroxine (T4) is one of the main hormones produced by the thyroid gland and plays a role in regulating metabolism, growth, and development. Most circulating T4 is bound to proteins such as thyroxine-binding globulin (TBG), while a smaller fraction circulates in free form. A Total T4 test measures both the bound and free fractions.

• Thyroid function assessment: Supports evaluation of thyroid hormone status alongside TSH and other laboratory findings.
• Assessment of hypothyroidism: Reduced T4 levels may be observed in some cases of hypothyroidism.
• Assessment of hyperthyroidism: Elevated T4 levels may be associated with hyperthyroidism.
• Thyroid follow-up: Allows results to be compared across clinical assessments as directed by the treating clinician.
• Clinical laboratory testing: Intended for laboratories requiring quantitative Total T4 measurement in human samples.

Clinical note: Total T4 results may be affected by changes in hormone-binding proteins, including those associated with pregnancy or certain medications. Results should therefore be interpreted in the context of the patient's clinical status, the laboratory reference range, and other thyroid tests. Free T4 measurement may provide additional information when indicated.

Important Considerations Before Purchasing

Before ordering, compare the kit's technical specifications with the laboratory's requirements and analyzer configuration. Important checks include:

• Reviewing the instructions for use (IFU), including calibration and quality-control requirements.
• Confirming storage conditions, expiration date, and reagent preparation procedures.
• Checking the manufacturer's stated measuring range, reporting units, and analytical performance.
• Verifying compatibility with the specific CLIA PV 1800 analyzer used by the laboratory.
• Considering factors that affect Total T4 interpretation and whether TSH or Free T4 testing may also be required.
