The Diagnostic Competence of Glial Fibrillary Acidic Protein in Mild Traumatic Brain Injury and Its Prognostic Value in Patient Recovery

AIM: To show whether the glial fibrillary acidic protein (GFAP) levels are significantly higher in the serum of patients with mild traumatic brain injury or not. MATERIAL and METHODS: The level of serum GFAP was measured in 176 patients suffering from brain trauma. The ability of GFAP in predicting the presence of intracranial lesions and the need for neurosurgical intervention was analyzed using the area under the receiver (AUC) operating characteristic (ROC). By passing three months from mild TBI, the Post-Concussion Symptoms Questionnaire (PCSQ) as well as the physical and mental evaluations were performed using the SF-36 questionnaire. RESULTS: Of 176 patients included, 79.5% had no complications and symptoms by passing three months from traumatic brain injury. The AUC for GFAP was 72.6%, which revealed a good accuracy in predicting the need for neurosurgical intervention. CONCLUSION: GFAP, as a predictive factor in people with mild TBI diagnosis who need neurosurgical operation, expressed a favorable diagnostic effect.
