Abstract
Background: Delayed in diagnosis and treatment of tuberculosis will increase the risk of MDR TB. WHO recommends Xpert MTB/RIF as
 diagnostic tools to identify MDR TB. Availability of Xpert MTB/RIF is still limited, another diagnostic tool is needed. Neutrophyl lymphocyte
 ratio (NLR) was presumed to be able to identify the probability of MDR TB. The aim of this study is to evaluate the comparison of NLR in tuberculosis
 and MDR TB patients.
 Methods: This is an analytic descriptive study with case series approach in Adam Malik General Hospital Medan. This study held since
 January – December 2015 with number of sample as much as 100 bacteriological confirmed TB patients and 100 MDR TB patients. We
 performed leukocyte differential count from peripheral blood examination to obtain NLR
 Result: Mean NLR of TB patient 4.62±2.37 and MDR TB 3.28±1.44. There was significant difference of NLR between both groups using
 Mann-Whitney test (P=0.001). The cut off value by ROC analysis was 2.91 with sensitivity, specificity, positive predictive value, negative
 predictive value and accuracy was 77%, 50%, 60.6%, 68.4% and 63.5% respectively.
 Conclusion: There was significant difference of NLR between bacteriological confirmed TB patients and MDR TB patients. Value of NLR
