Scientific Data for Colon from Supplier (Instrument and Reagent)
Method:
Fluorescence quantitative immunoassay.
Detection limit:
Less than or equal to 2.0 ng/mL.
Precision:
The within assay CV is ≤ 10%. The between assay CV is ≤ 15%.
Measuring Range:
2.0~500.0 ng/mL
Validation-Active Information:
- EQA:
- Inter-laboratory validations
- Periodic according to validation schedule.
- Event-triggered: QC, Calibration, New materials.
Precision:
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.
In range results:
CEA levels that are less than or equal to 4.7 ng/mL are considered at the normal range.
Out of range results:
Any result greater than 4.7 ng/mL ranges would be considered abnormal. Those with slight to moderate CEA may be at risk for non-malignant disease of the intestine, pancreas, liver, and lungs. However, this test alone cannot be used to diagnose cancer. It is also important to note that smoking can lead to elevated levels.
