CEA Carcinoembryonic Antigen detection kits CLIA

The kit has been designed for the quantitative determination of Carcinoembryonic Antigen (CEA) in human serum.
The method can be used for samples over the range of 0.4-150.0 ng/mL.
The test has to be performed Taizhou Zecen Biotech Co., Ltd. model CIA 600, CIA 600Plus, CIA
1200, CIA 1200M, CIA 1800, CIA 2800 and POClia 8, POClia minus, POClia plus, POClia auto
automatic chemiluminescence analyzer. Shenzhen IncreCare Biotech Co., Ltd. model Shine i1900、Shine i2900 automatic chemiluminescence analyzer.

PRINCIPLE OF THE TEST Sandwich method: 

CEA Antibody labeled by FITC and CEA Antibody pair labeled by AP bind with the CEA antigen in  the sample, control or calibrator and form sandwich complex. Then add the magnetic beads binding  with Anti-FITC, through the specific binding between the FITC and Anti-FITC, the complex will be  bound by the magnetic beads. Then the entire complex will be captured by the external applied  magnetic field and separate from the unbound substance. After washing, add the substrate. The  substrate will be catalytically cracked under the action of the enzyme, and form an unstable  intermediate in excited state. When the intermediate in excited state returns to the ground state, it will  issue photons and make a light-emitting reaction. Then the CLIA analyzer will measure the luminous  intensity and count the results through software by comparing the luminous intensity with the cutoff  value to determine whether the corresponding antibody exists. 


1) Traceability 

To perform an accurate calibration, we have provided the test calibrators standardized against the  National Standard for Carcinoembryonic Antigen Immunoassay by National Institutes of Food and  Drug Control.

2) 2 or 6 Point Recalibration Via the measurement of calibrators, the predefined master curve is adjusted (recalibrated) to a new,  instrument-specific measurement level with each calibration. 

3) Frequency of Recalibration 

⚫ After each exchange of lots (Reagent Integral or substrate Reagents). 

⚫ Every week and/or each time a new Integral is used (recommendation). 

⚫ After each servicing of the CIA Fully Auto analyzer. 

⚫ If controls are beyond the expected range.
