[Product Introduction]
  This product does not require any instruments and is used to detect Lepidol residues in urine and animal tissues.The entire detection process only takes about 3-5 minutes,with a sensitivity of 3ng/ml(3ppb).
  Product composition
  Quick detection card for Laike colloidal gold(50 pieces/box)
  Dropper(1 piece/bag)
  Desiccant(1 piece/bag)
  Sample processing
  1.Urine
  Collect approximately 5ml of urine using a dry and clean centrifuge tube or appropriate container.If not tested immediately,urine samples can be stored for 24 hours at 2-8℃refrigeration,and attention should be paid to avoid spoilage,which may cause failure or contamination.
  2.Animal tissues and viscera
  Take more than 4 grams of lean meat or visceral samples(the finer the better)and place them in a 5ml centrifuge tube(preferably filled with three-quarters of the tube).Tighten the tube cap(do not let water enter the tube).Heat the centrifuge tube containing the sample in a water bath above 90℃for 10 minutes(the meat is cooked thoroughly),then remove and cool to room temperature;Take out the tissue exudate,add one volume of diluent,mix well,and wait for testing
  [Usage Steps]
  1.Before conducting the test,read the user manual thoroughly and restore the test card and sample solution to room temperature before use.
  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 draw the solution of the sample to be tested,and vertically add 2 drops into the sampling hole.After adding the sample,start timing.
  4.The results should be read within 3-5 minutes,and interpretation at other times is invalid.Determine the results based on the schematic diagram.

  S negative(-):Two purple red bands appear.Indicates that the concentration of Lake in the sample is below 3ppb,or it does not contain.
  S positive(+):If there is no color development in the T-line,it indicates that the Laike concentration in the sample is higher than 3 ppb.
  Invalid s: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.Urine droppers should not be mixed to avoid cross contamination;
  5.If there is sediment or turbidity in the urine sample,please centrifuge before testing;
  6.Please contact the supplier for any issues encountered during the experiment.
  7.If you need to directly test the standard,please prepare it with mixed negative pig urine.
  [Storage and expiration date]
  The original packaging should be stored at 4-30℃,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.
