Cadmium Colloidal Gold Rapid Detection Card Instruction Manual

Product Number: YB138R01K

Summary

Cadmium (Cadmium, Cd) is a accumulative heavy metal element, even at very low concentration levels, it will cause harm to the human body and other organisms. Cadmium can accumulate in the human body through the food chain, which can cause various acute and chronic toxic effects in the human body. Cadmium in food can cause connective tissue damage, reproductive system dysfunction, kidney damage, teratogenic and carcinogenic hazards, and even affect children's growth and intellectual development. This product is suitable for enterprises, testing institutions, supervision departments and other on-site rapid detection.

Detection principle

This product adopts the principle of competitive inhibition immunochromatography. The heavy metal cadmium in the sample binds to the specific antibody labeled with colloidal gold, which inhibits the binding of the antibody to the antigen on the NC membrane test

line (T line), resulting in a change in the color depth of the test line. Regardless of whether the sample contains the substance to be tested, the quality control line (C line) will develop color on

to show that the detection is effective.

Scope of application

This product is suitable for the qualitative detection of heavy metal cadmium residues in aquatic products and livestock and poultry tissue samples.

Note: For the type of test sample, refer to the national standard GB2763-2021.

precautions

(1) Before each sample, the knife that shredded the sample needs to be cleaned to avoid cross-

(3) Please follow the test steps for testing. Do not touch the color-developing area of the test strip during operation to avoid direct sunlight and direct blowing of electric fans.

(4) Please use the sample as soon as possible after processing. If the time is too long, you need to re-process the sample for re-testing.

(5) The solution of the sample to be tested needs to be clarified, otherwise it will easily lead to abnormal phenomena such as inconspicuous color development, which will affect the judgment of the experimental results.

(6) Products that have expired or damaged aluminum foil bags cannot be used. Please use the test card immediately after unpacking.

(7) This product is a one-time product. Do not reuse or mix test cards from different batches.

(8) When a positive result appears, it is recommended to re-test. The test results of this product are for reference only. If you need confirmation, please refer to the relevant national standards and methods.

(9) During product evaluation, if the standard product needs to be tested directly, it needs to be prepared with the special dilution solution in the kit.

(10) Tap water, distilled water, purified water or deionized water cannot be used as a negative control.
