15% Need a Thyroid Blood Test?
The thyroid is the largest endocrine gland in the body. It secretes two hormones, T3 and T4.
Why get a Thyroid Test?
The occurrence of thyroid problems is influenced by several factors: increased levels of stress. This chaotic diet does not bring the necessary nutrients, neglecting the first signs of illness and the absence of a periodic medical check-up.
5 Biomarkers:
- TSH: it measures the stimulating hormone amount.
- TT3 is one of the main thyroid hormones.
- TT4: it measures the amount of thyroxine produced by the gland and helps control metabolism and growth.
- FT3: it measures the amount of free triiodothyronine.
- FT4: It helps you understand how well your gland works.

Scientific Data from the Thyroid Kit 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%. Also, 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 this Thyroid check is based on the relative deviation, which is the average deviation from the actual result value.
The precision relies on the within-assay and between-assay coefficients of variations. The within-assay coefficient of variations is the variance of the result value if the same sample was analysed again. The between-assay coefficient is the variance of the result value if the same sample was reprocessed from the beginning again.
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
Furthermore, adults with euthyroid or normal production and serum levels are expected to have normal or in-range results.
Out-of-range results:
Also, any results outside the listed reference ranges would be considered abnormal. And the person may be at risk for hypothyroidism, hyperthyroidism, and other issues.
