Coxiella burnetti, Pre-coated (+/-) is for detection of select agents (and simulants) in environmental samples.
This product is not for diagnostic use of clinical samples.
The Plus/Minus (+/-) ELISA format utilizes a positive row of capture antibody above a negative row of normal, same species antibody. The lower result can be subtracted from the top result to produce an adjusted result. This is the preferred method for complex sample matrices.
