More biomarkers making diagnostics better

The first time you learn about a biomarker being able to diagnose a condition, you hope it’s not you, getting diagnosed with congestive heart failure. If your doctor finds elevated levels of B-type natriuretic peptide (BNP) in a blood test, she knows immediately to suspect heart failure.

Researchers are now discovering more biomarkers to help diagnose and manage a variety of conditions. Mild traumatic brain injury (mTBI) or concussion, for instance, can be easily confused with potentially passing phenomena such as intoxication or delirium, according to an article online in MedPage Today. But mTBI and concussion require urgent and decisive care. A new study has found that two biomarkers can be measured in order to differentiate mTBI or concussion from other conditions and thus signal doctors to institute appropriate treatment.

In a study of patients treated at a level 1 trauma center, glial fibrillary acidic protein (GFAP) beat out ubiquitin C-terminal hydrolase L1 (UCH-L1) for detecting TBI, CT lesions, and neurosurgical intervention…reported online in JAMA Neurology.

Now they’re studying how quickly a marker can be detected and over how long a period it can be used so they can tell how accurately these biomarkers will allow doctors to gauge an injury.

Non-invasive. Always good news.
