  Karen Lake Sardine Trinity Colloidal Gold Rapid Detection Card

  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】

  S 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 longitude of lean meat in the sample is above the detection limit.
  Invalid:No quality control C-line appears,indicating incorrect operation or detection card failure.In this case,carefully read the manual again and retest with a new detection card.If the problem persists,immediately stop using this batch of products and contact the local supplier.
  Limitations of testing methods
  1.This product is only a qualitative detection method and its concentration cannot be determined.
  2.This product is only for preliminary screening use,and the test results cannot be used as a basis for diagnosis.Two analytical methods must be used to determine the results,and gas chromatography-mass spectrometry(GC/MS)is currently the better method for confirming analysis.
  Precision
  At the same time,150 samples,including 94 negative samples and 56 positive samples,were tested using this product and Karen,Lake,and Sardine liquid chromatography-mass spectrometry tandem mass spectrometry.The test results showed that the conformity rate between this product and mass spectrometry was 100%.

  【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.
  [Storage and expiration date]
  The original packaging should be stored at 4~40℃,in a cool,dark,and dry place,and should not be frozen;The validity period is 24 months.The expiration date and batch number can be found on the outer packaging.
  Products recommended in accordance with the evaluation report of the New Ministry of Agriculture and Rural Affairs
