Biomarker Assay
Biomarker Assay is a diagnostic or screening method used to obtain clinically useful information about a disease process, body function, microorganism or biological marker.
Clinicians request biomarker assay when its result can help answer a defined question about diagnosis, risk, disease activity or treatment response.
Correct specimen collection, patient preparation and technical performance can materially influence the reliability of biomarker assay.
The result is interpreted against reference standards and the patient's pre-test probability rather than being treated as an isolated diagnosis.
Abnormal findings from biomarker assay may lead to confirmatory testing, imaging, tissue sampling, specialist referral or a change in management.
Limitations such as false-positive, false-negative or indeterminate results should be considered when explaining biomarker assay to patients.
