Background: Haematotoxicity occurs following acute and chronic low dose exposures to lead. This study aimed to assess the association between occupational lead exposure and haematological parameters among roadside and organized panel beaters in Enugu Metropolis, Nigeria, 2018-19. 
Materials and Methods: This was a cross-sectional and analytical study of 428 roadside and organized panel beaters. A multistage sampling technique was used to select participants. Blood lead and haematological parameters were analyzed using Atomic Absorption Spectrometer at 238.3nm wavelength and Mindray Auto Haematology Analyzer, respectively. Comparative analyses were performed using Chi-square, Man Whitney U-test, T-test, correlation, and statistical significance.
Results: All the haematological parameters on both sectors of panel beaters had mean values within the normal reference values. 7 (3.3%) on both sectors had abnormal haemoglobin and 4 (1.9%) and 3 (1.4%), respectively, had abnormal WBC. There was weak linear correlation among roadside and organized panel beaters of blood lead: Hb (r= -0.061, P= 0.371) and (r= 0.026, P= 0.709), RBC (r= -0.036, P= 0.596) and (r= -0.004, P= 0.956), and TWBC (r= -0.044, P= 0.524) and (r= 0.092, P= 0.180), respectively.
Conclusion: Haematological parameters on both sectors were found to be within the normal reference range. There was a non-significant weak linear correlation between blood lead and the parameters. Haematological investigations should be included as part of routine biomonitoring in occupational health practice as an indicator of lead exposure.
