FYL Urine Screening Strip
FYL Urine Screening Strip (芬太尼Fentanyl尿检试纸条) is a one-step lateral flow rapid qualitative diagnostic test kit, based on the Colloidal Gold Chromatographic Immuno Competitive Binding principle, which is used to detect drug Fentanyl in human Urine specimen.
Please refer to the Instruction for Use (IFU) of the FYL Urine Screening Strip.
Detailed information of FYL Urine Screening Strip
- General and Technical information of this FYL test kit;
- Packing specification of this FYL Dipstick style test kit (gross weight in full kit package and in bulk packing);
- Specimen used to carry out the assay, and the requirements on specimen collection, storage and processing; and,
- Specific immuno assay principle used in this Fentanyl Test Kit.
Main technical information of this FYL test kit is listed in the following table:
|Catalog No.:||FYL 6131|
|Description:||FYL Urine Screening Strip|
|No. of Step:||One Step|
|Reading Time:||5 Minutes|
|Quan. or Qual.:||Qualitative|
|Assay Principle:||Colloidal Gold Chromatographic Immuno Competitive Binding|
The standard kit size of Fentanyl Dipstick test kit is 100 tests per box; 48 boxes per carton.
To save freight cost, sometimes bulk packing is used, meaning test strip, cassette or multi-test panel is packed in single aluminum pouch; 50 or 100 pouches in one plastic bag; and then plastic bags are packed in cartons along with the unfolded boxes for the test kits. In this way, the customers can easily pack the tests into test kits after receiving the bulk packed goods.

To carry out the assay with a FYL Urine Screening Strip, Urine should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.
A urine specimen must be collected in a clean and dry container.
For hormone test such as HCG prenancy test, the first urine specimen in the morning is preferred since it generally contains the highest concentration of hormone, although urine specimens collected at any time of the day may be used.
Urine specimens exhibiting visible particles should be centrifuged, filtered, or allowed to settle to obtain clear specimen for testing.
Urine Storage Condition
Urine specimens may be stored at 2-8°C for up to 48 hours prior to testing. For long-term storage, specimens may be frozen and stored below -20°C.
Frozen specimens should be thawed and mixed before testing.
Colloidal Gold Chromatographic Immuno Competitive Binding method is used in this FYL Urine Screening Strip to detect the drug Fentanyl in human Urine specifically. The introduction of this Colloidal Gold Chromatographic Immuno Competitive Binding testing principle is given blow.
Drug abuse test kits are based on the Lateral Flow Competitive Binding rapid test principle.
In the test kit, drug-protein conjugates (purified bovine albumin) are immobilized in the test line region. And the drug specific antibody conjugated with colloidal gold particles is put in the membrane of the sample adding region.
During testing, when the urine specimen is added to the sample adding region, the antibody conjugate particles will come into the urine specimen, where the antibody conjugate will react with the drug. If there is no target drug in the urine specimen, or the concentration is lower than the cut-off, the drug can not bind all the binding sites of the drug specific antibody colloidal gold conjugate.
The unbonded colloidal gold conjugate will be captured by the immobilized drug in the testing line region. When the antibody conjugated colloidal gold particle congregate, a red or pink color will develop, indicating a negative result.
If the concentration of the drug is higher than the cut off value of the test kit, the drug will saturate all the binding sites of the antibody conjugate. Then, when the mixed fluid moves to the test region under capillary effect, there will be no free antibody particles to bind with the immobilized drug, and no color will develop, indicating a positive result.
