Product Description
Human D-Dimer Rapid Test Kit (Dry Immunofluorescence Assay) Insert
Product Name:Human DDimer Rapid Test Kit (Dry Immunofluorescence Assay)
Packaging Details：50T/box Cat#: CG01C09S-50 Lot.: lot. specific
Intended Use: This immunoassay kit allows for the in vitro quantitative determination of Human DDimer in serum, plasma and other biological fluids.
Primary Structure and Composition
Kits are composed of test cards and specifications. Test cards consist of plastic shell and strips. Primary components of casettes are sample pad, fluorescence pad NC membrane and absorbent paper.
Test Principle
Kit Principle: Human DDimer rapid test kit (dry fluorescent method)developed by our company contains two anti-Human DDimer monoclonal antibodies（capture&detection）with high specificity and sensibility. Anti-Human DDimer detection antibody is labeled by nano fluorescent microspheres and is coated on the fluorescence pad; Anti-Human DDimer capture antibody is coated on T line of NC membrane.
| If the sample contains Human DDimer protein, the Human DDimerprotein in the sample will form a “nano fluorescent microspheres – Anti-Human DDimer detection antibody – Human DDimer protein – Anti-Human DDimer capture antibody” sandwich complex and then agglomerate to generate fluorescent signal on the T line. The signal would be analysed by the POCT analyzer to convert to the concentraton of Human DDimer in the sample. |
The fluorescent pad was also coated with chicken IgY labeled by nano fluorescent microspheres, which will be combined with the Rabbit anti chicken IgY antibody precoated on the C line when samples pass. The signal of C line should be constant and then indicate the validation of the test.
Complement Instrument Principle: The detection card is inserted into POCT immune fluorescence quantitative analyzer of HG-98 /CagenBio-I, II, and III type. The instrument measuring system automatically scan the label and the signal to be detected. Then the optical signal is measured and analyzed, and the concentration of the measured substance is obtained.
Storage& Transport Condition
Storage Condition：Store in dry and cool place in 4~30℃；
Transport Condition：Prevent exposition, extrusion and moisture in general transport
Manufacture Date and Shelf Life
Manufacture date：on the out package
Shelf Life：12 months when 4~30℃ in the sealed pouch
Applicable Instrument
It is applicable in HG-98type/CagenBio-I type、II type、III type POCT immunofluorescence instrument.
Specimens Collection and Preparation
- Collect 1 to 2 ml fasting venous blood to put in the coagulation blood vessels, and collect 500μL serum when serum is precipitated.
- It is recommended to collect and detect blood in drying tube with stopper.
- Avoid using sample of hemolysis or milk condition.
- Serum samples can be stored at 2-8℃ for 7 days. For prolonged storage, please keep it at -20℃ and avoid repeated freezing and thawing.
Reference Ranges
Reference normal value is 500 ng/ml and it is suggested that the hospital establish their own normal value and serum of quality control.
Assay procedure
- The test card was taken out from the reagent box, and add 60μL serum and plasma samples to the well of the test card.
- Keep it still for 10 min in room temperature.
- After 10 minutes, put the test casette into the immune fluorescence quantitative analyzer to read data.
- Immune fluorescence quantitative analyzer will measure and analyze optical signal, and the concentration of material will be quantified;
- It is proposed to make calibration with assorting reagents or traceable calibration and calibration type is linear.
Specificity
1.The box should be clean and not broken, and the casettes appear no stain or scratches.
2.Sensitivity: The minimum detection limit of human Human DDimer is typically 1 ng/ml.
3.Accuracy: The recovery rate of deviation is less than ±15%.
4.Linear range: 1~2000 ng/ml.
5.Precision: repeatability CV＜15%, and inter batch difference R＜20%.
Important Note:
- The product is disposable, and can not be used repeatedly.
- The test kit should be used within one hour after taking out, and the casettes taken out should not be put back.
- Please accomplish numerical reading within 10 minutes because the detection results will be not accurate when the test casettes are put for long time.
- The products are only applicable in in vitro detection.
- Set up the relevant procedures in the immune analyzer, and the report is invalid when the quality control line is not detected, then it is recommended to retest.
- Hook effect will appear when concentration of Human DDimer protein in the serum of patients is too high, the sample should be diluted for assay, and the dilution factor should be multiplied.
