This study aimed to find correction factor to convert two conventional methods of hemoglobin determination (acid hematin and microhematocrit derived values ) to the gold-standard method called the cyanmethemoglobin method. A total of one hundred percent patients from a primary hospital in San Pedro, Laguna were enrolled in the study through purposive sampling. They were equally divided to both genders ranging from 20 to 60 years of age. Comparison of the means between the three methods shows a significant difference in their values. Multiple regression analyses between cyanmethemoglobin method and acid hematin and cyanmethemoglobin method and microhematocrit- derived hemoglobin values acid hematin values were done. The correction formula to convert acid hematin values  to cyamethemoglobin was 6.74 + 0.65 multiplied by acid hematin values for  males and -0.6 + 1.24 multiplied by the acid hematin value for females. Similarly, the correction  formula over to convert microhematocrit-derived  hemoglobin values to cyanmethemoglobin was 9.4 + 0.40 multiplied by microhematocrit derived value for males and 1.10 + 0.98 multiplied by microhematocrit derived hemoglobin value for females. The formulae revealed a mean percent difference of 0% when used. These correction factors would be of great value to the achievement of accurate hemoglobin values at a very low cost. The study wuld equally benefit physicians, healthcare workers, owners of health care facilities and most especially, the poorest of the poor society.
