However, its utilization among young adults, particularly undergraduates, is very low. The aim of the present study was to determine the prevalence and predictors of non-uptake of VCT among undergraduates. Methods: A cross sectional study using quantitative methods was conducted. Using simple random sampling, three faculties were selected out of nine and 422 respondents were selected from three faculties. Interviews were conducted using pre-tested semi-structured questionnaires. Data analysis was done using statistical package for social sciences version 20. Prevalence was measured by the percentage of respondents that had never used VCT. Analytical statistics were done using chi-square test to measure strength of association between VCT uptake and knowledge and attitude of respondents. Association with P-value < 0.05 was considered significant. Logistic regression was used to identify predictors of non-uptake of VCT. The associations were presented as odds ratios (OR) and 95% confidence intervals. Results: Overall, 59.3% of respondents were knowledgeable about VCT while majority, 64.7% had negative attitude towards it. Knowledge (X2 = 9.89, P-value < 0.001) and attitude (X2 = 10.78, P-value < 0.001) showed statistically significant association with VCT uptake. The prevalence of non-uptake of VCT among the respondents was 82.7%. Ignorance, fear of positive test, stigma and discrimination were found to be strong predictors of non-uptake of VCT. OR 1.874 (1.058 - 3.289), P < 0.001; OR 2.455 (1.308 - 4.608), P < 0.000 and OR 2.318 (1.299 - 4.128), P < 0.000 respectively. Conclusions:
