Pregnancy Relaxin Test Kit (RLN)

Test principle of the Pregnancy Relaxin Test Kit

This product uses rapid immunochromatography technology to detect the level of relaxin in the whole blood or serum of canine and feline. After the diluted sample was dropped into the sample well, if there was RLN in the sample, it would specifically bind to the recombinant protein labeled with colloidal gold to form a complex that moved along the chromatographic membrane and was captured by the antibody coated on the membrane, showing a wine red line on the detection line (T). If there is no RLN in the sample, no visible lines will be formed at position T. No matter the result is negative or positive, the C line should be colored, otherwise the result is invalid.

Negative: In the test window, only one fuchsia-colored line appear next to “C”.
Positive: In the test window, two distinct colored lines appear next to “T” & “C” simultaneously.
Invalid: No color line visible next to “C”.

NOTE: Invalid test results can be caused by a variety of reasons and should be re-tested.
