Methaemoglobin Estimation

What is the Methaemoglobin Estimation Blood test?

 This test measures methaemoglobin levels in the blood, a form of hemoglobin that cannot carry oxygen efficiently. Elevated levels can lead to tissue hypoxia, causing cyanosis and other symptoms.


Why is this test performed?

 It is used to diagnose methemoglobinemia, a condition caused by exposure to oxidizing agents, genetic enzyme deficiencies, or certain medications.


How is the test conducted?

 A blood sample is collected and analyzed using spectrophotometry to determine methaemoglobin concentration.


What do abnormal results indicate?

 Increased methaemoglobin levels suggest impaired oxygen transport, often due to chemical exposure, medication effects, or congenital enzyme defects.


What are the next steps if levels are high?

 Treatment may involve methylene blue administration, oxygen therapy, or avoiding exposure to causative agents.
