Total T3 CLIA Test CE

The Total Triiodothyronine (T3) Chemiluminescence ImmunoAssay (CLIA) Test is a chemiluminescence-based immunoassay for the quantitative detection of T3 in human serum or plasma (Sodium heparin or K2EDTA, or K3EDTA) using the ALTA CLIAlyzer.

Thyroid disease is very common on a global level and studies have shown that the prevalence of undiagnosed thyroid disorder is high. Thus, quantification of markers that reflect thyroid function is very important.

Thyroid stimulating hormone (TSH) controls the production of the thyroid hormones thyroxine (T4) and 3, 5, 3’ triiodothyronine (T3), which play an important role in the regulation of metabolism.

Thus, testing of thyroid function commonly encompasses TSH and a combination of the thyroid hormone (T3/T4, fT3/fT4) assays.

  • Individual ready-to-use cartridges
  • Combines competitive immunoassay technique with enzyme catalyzed chemiluminescence detection
  • Sample volume: 75 μL

Range

Working range: 0.3-10 nmol/L.

Detection Limits

Limit of Detection (LOD): 0.3 nmol/L.

Precision

Intra-lot Precision

CV less than 8%

Inter-lot Precision

CV less than 15%

Accuracy

Accuracy of ± 10% in comparison to the control

Linearity

Linearity from 0.3 and 10 nmol/L.

Specificity

No significant cross-reactivity was observed when T4 (500 ng/mL) or rT3 (50 ng/mL) were added to the T3 Calibrator CAL1 respectively. The results of T3 in these samples were less than 3.072 nmol/L.

Interference

No significant interference was detected up to the concentrations mentioned below:

SubstanceConcentration
Hemoglobin≤500 mg/dL
Bilirubin≤20 mg/dL
Triglyceride≤1500 mg/dL
Total Protein≤10 g/dL
Rheumatoid Factor≤1500 IU/mL

HAMA Interference 

Patient specimens containing human anti-mouse antibodies (HAMA) may give falsely elevated or decreased values.  Although HAMA-neutralizing agents are added, extremely high HAMA serum concentrations may occasionally affect the results.
