Protocol for the study of bedside CSF analysis by urinary reagent strips and comparison with traditional laboratory measurements in a tertiary care centre in rural India

Abstract

Abstract* Background Meningitis is an infection of leptomeninges. It is an emergency life-threatening condition that requires prompt treatment initiation. Diagnosis is the rate-limiting step because cerebrospinal fluid (CSF) analysis requires experienced personnel. Therefore, this study was conducted to assess the utility of urinary reagent strips for the rapid bedside diagnosis of CSF glucose, proteins, and leukocytes. Objective To determine the efficacy of a urinary reagent strip for bedside analysis of cerebrospinal fluid (CSF) samples. Methods This prospective comparative study will be conducted in the Department of Neonatology and Pediatrics, Jawaharlal Nehru Medical College, Sawangi, Wardha. CSF samples from patients suspected of infection of the central nervous system (CNS) and awaiting diagnosis will be subjected to semi-quantitative analysis using a urinary reagent strip (for glucose, proteins, and leukocytes). The results were compared with the laboratory results of the individual samples. Result After completing the study, we determined the efficacy of the urinary reagent strips in bedside estimation of CSF glucose, protein, and leukocyte levels in terms of sensitivity, specificity, positive and negative predictive values, and diagnostic accuracy. Conclusion This study provides insight into the utility of urinary reagent strips for rapid bedside diagnosis of CSF samples from patients suspected of having an infection.
