It is based on colour comparison using a hemoglobinometer and is commonly used in medical laboratories and diagnostic centres.<br><\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Complete Answer:<\/strong><br><\/p>\n\n\n\n<p>Sahli\u2019s method, also known as the acid hematin method, involves converting haemoglobin into acid hematin by mixing a blood sample with hydrochloric acid (HCl). The solution is then compared against a calibrated colour scale to determine the haemoglobin concentration.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Steps of Sahli\u2019s Method<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Blood Sample Collection:<\/strong> A few drops of blood are taken using a Sahli pipette.<\/li>\n\n\n\n<li><strong>Addition of HCl:<\/strong> The blood is mixed with 0.1N hydrochloric acid, which converts haemoglobin into brown-coloured acid hematin.<\/li>\n\n\n\n<li><strong>Dilution:<\/strong> Distilled water is added dropwise until the colour matches the standard comparator.<\/li>\n\n\n\n<li><strong>Reading the Result:<\/strong> The haemoglobin concentration is then read directly from the hemoglobinometer.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Advantages of Sahli\u2019s Method<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Simple and Cost-effective:<\/strong> Requires minimal equipment and is easy to perform.<\/li>\n\n\n\n<li><strong>Widely Used:<\/strong> Commonly used in resource-limited settings and small laboratories.<\/li>\n\n\n\n<li><strong>No Need for Complex Instruments:<\/strong> Unlike automated analyzers, this method relies on visual comparison.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Limitations of Sahli\u2019s Method<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Subjective Interpretation:<\/strong> The accuracy depends on the person comparing the colour.<\/li>\n\n\n\n<li><strong>Less Precise Than Modern Methods:<\/strong> Automated techniques like spectrophotometry provide more precise results.<\/li>\n\n\n\n<li><strong>Affected by Lighting Conditions:<\/strong> External light sources may influence the perception of colour.<\/li>\n<\/ul>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Fun Fact About Hemoglobin<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Did you know?
