Use

The Methemoglobinemia Evaluation test is used for diagnosing methemoglobinemia and sulfhemoglobinemia and assessing possible hereditary causes. This test is useful for differentiating these conditions from other cyanotic disorders, such as congenital heart disease. Methemoglobin forms when the hemoglobin molecule iron is in the ferric form instead of the functional ferrous form, leading to the condition methemoglobinemia with levels greater than normal. The test results provide information essential for managing these disorders, particularly for identifying hereditary causes like deficiencies in cytochrome b5 reductase or structure anomalies in hemoglobin, known as M-Hbs.
