What is the Scientific Data from Instrument and Reagent Supplier?

Technology Method:

Fluorescence quantitative immunoassay

Limit of Detection:

  • TSH: 0.1 mIU/L
  • TT3: 0.5 nmol/L
  • TT4: 5 nmol/L
  • FT3: 1 pmol/L
  • FT4: 0.3 ng/mL

Precision and Accuracy:

The relative standard deviation is ≤ 15%. The within-assay CV and the between-assay CV are less than or equal to 15%.

Measuring Ranges:

  • TSH: 0.1~100 mIU/L
  • TT3: 0.5-10 nmol/L
  • TT4: 5-300 nmol/L
  • FT3: 1-50 pmol/L
  • FT4: 0.30-100.00 pmol/L

Validation-Active Information:

  • EQA: Yes
  • Inter-laboratory validations
    • Periodic according to the validation schedule
    • Event-triggered- Qc/Calibration/New materials/Batch

Accuracy and Precision:

The accuracy of these Thyroid Profile blood tests is based on the relative deviation. The relative deviation is the average deviation from the actual result value.

The precision relies on the within-assay coefficient of variations and the between-assay coefficient. The within-assay coefficient of variations is the variance of the result value if the same test was analysed again. The between assay coefficient is the variance of the result value if the same sample was reprocessed from the beginning again.

TSH, TT3, TT4, FT3, and FT4 Detection:

TSH, TT3, TT4, FT3, and FT4 are measured from the serum, plasma, or whole blood samples.

In range results:

  • TSH: 0.3~4.2 mIU/L
  • TT3: 1.23-3.07 nmol/L
  • TT4: 66-181 nmol/L
  • FT3: 3.10-6.80 pmol/L
  • FT4: 12.00-22.00 pmol/L

Adults who are euthyroid or have normal thyroid production and serum levels are expected to have normal or in-range results.

Out-of-range results:

Any results outside of the listed reference ranges would be considered abnormal, and the person may be at risk for hypothyroidism, hyperthyroidism, and/or other thyroid issues.
