3-in-1 DOA 3P Urine Screening Panel
DOA 3P Urine Screening Panel (毒品尿检试纸卡三联板) 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 Abuse 3P in human Urine specimen.
Please refer to the Instruction for Use (IFU) of the DOA 3P Urine Screening Panel.
(Note: for different drug test kits of multi-drug test panels, the IFUs are of the same version, including information of all optional parameters.)

Main technical information of this DOA 3P test kit is listed in the following table:
|Catalog No.:||DOA 603|
|Description:||3-in-1 DOA 3P Urine Screening Panel|
|No. of Step:||One Step|
|Reading Time:||5 Minutes|
|Cut Off:||Ref. to single drug|
|Quan. or Qual.:||Qualitative|

The standard kit size of Drug Of Abuse (DOA) Panel test kit is 20 tests per box; 32 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 DOA 3P Urine Screening Panel, 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 DOA 3P Urine Screening Panel to detect the Drug Abuse 3P 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.
