AI Overview
Key Features and Specifications:
- Methodology: Generally based on competitive immunofluorescence assay technology.
- Detection Time: Fast results, often within 15 minutes, suitable for Point-of-Care Testing (POCT).
- Sample Type: Human serum, plasma, or whole blood.
- Accuracy: Often features an accuracy within ±15%.
- Range of Detection: Typical, linear range is 0.3-100 pmol/L (approx. 0.02-7.77 ng/dL).
Usage and Application:
- Purpose: Measures free thyroxine, the active form of the hormone, to determine how well the thyroid gland is functioning.
- Application: Used for screening, diagnosing thyroid dysfunction, and monitoring treatment.
- Procedure: Requires small sample volumes (e.g., 100 L) and uses specialized portable analyzers to read the test cards, such as those from Getein Biotech or Lansion Biotech.
Important Notes:
- These tests are for professional in-vitro diagnostic use only and should be conducted by trained personnel.
- They should not be used as the sole criterion for treatment decisions.
- Results should be interpreted alongside clinical symptoms and other thyroid tests (e.g., TSH).
- Fasting is generally not required for thyroid tests, though some providers may recommend it.
