An example is the traumatic brain injury (TBI) blood-based biomarker test consisted of measuring the levels of neuronal Ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) and Glial fibrillary acidic protein (GFAP) to aid in the diagnosis of the presence of cranial lesion(s) among moderate to mild TBI patients that is(are) otherwise only ...
It is necessary to distinguish between disease-related and drug-related biomarkers.Disease-related biomarkers give an indication of the probable effect of treatment on patient (risk indicator or predictive biomarkers), if a disease already exists (diagnostic biomarker), or how such a disease may develop in an individual case regardless of the type of treatment (prognostic biomarker).
The mRNA-based disease diagnosis technologies have been applied to medical field widely in recent years, especially on early diagnosis of tumors (such as renal cell carcinoma, [2] hepatocellular carcinoma, [3] [4] breast cancer [5] and prostate cancer [6]). The technology can be applied to various types of samples depending on how easily the ...
The diagnostic procedures confirm if there is leukemia present, the extent of the leukemia (how far it has spread), and the type of leukemia. The diagnostic procedures are similar for the different types of leukemias: A bone-marrow aspiration and biopsy to look for and collect leukemia cells. In aspiration, a fluid sample is removed from the ...
The diversity of immunohistochemistry markers used in diagnostic surgical pathology is substantial. Many clinical laboratories in tertiary hospitals will have menus of over 200 antibodies used as diagnostic, prognostic and predictive biomarkers. Examples of some commonly used markers include: BrdU: used to identify replicating cells. Used to ...
For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.

For example, proteomics is highly useful in the identification of candidate biomarkers (proteins in body fluids that are of value for diagnosis), identification of the bacterial antigens that are targeted by the immune response, and identification of possible immunohistochemistry markers of infectious or neoplastic diseases.
