  Product composition
  Karen Lake Sardine Three in One Colloidal Gold Rapid Detection Card(40T/box)
  Dropper(1 piece/bag),desiccant(1 piece/bag)
  Sample processing
  Collect approximately 50ml of urine using a dry and clean centrifuge tube or appropriate container.If not tested immediately,the sample to be tested should be stored at 2-8℃and can be stored for 24 hours,taking care to avoid spoilage causing failure or contamination.If a positive result occurs,the sample should be packaged in bottles according to the legal procedure for confirmatory testing.
  [Usage Steps]
  1.Before testing,read the instruction manual completely.Before use,restore the test card and sample solution to room temperature of 4-30℃.
  2.Remove the testing card from the original packaging bag and use it as soon as possible within one hour after opening.
  3.Place the detection card flat,use a dropper to absorb the solution of the sample to be tested,slowly and vertically add 2-3 drops into the sample well,and start timing after adding the sample.
  4.The result should be read within 3-5 minutes,and interpretation at other times is invalid.Determine the result based on the schematic diagram.
  【Result judgment】

  Negative(-):Two purple red bands appear.Indicates that the sample does not contain lean meat or its concentration is below the detection limit.
  Positive(+):If the T-line does not show color,it indicates that the lean meat concentration in the sample is above the detection limit.
  Invalid:No quality control C-line appears,indicating incorrect operation or detection card failure.
  【Precautions】
  1.Please use the testing card once within its shelf life;
  2.Avoid direct sunlight and direct fan blowing during testing;
  3.Try not to touch the white film surface in the center of the detection card;
  4.Sampling droppers should not be mixed to avoid cross contamination;
  5.If there is precipitation or turbidity in the sample to be tested,please centrifuge before testing;
  6.Please contact the supplier for any issues encountered during the experiment.
