Bioanalytical assay such as nucleic acid hybridization and immunoassays are extremely important in a variety of fields, for example clinical diagnostic medicine and drug testing.

In nucleic acids and proteins detection, the use of nucleic acid hybridization, immunoreaction and small molecule-protein interaction offers desirable selectivity for the assays.

Objective To detect the status of CT and UU infection in local (STD)patients, and the value of measuring CT and UU with Nucleic Acid Amplification Hybridization Climb method.
