Laboratory screening of hemoglobinopathies

Area of Science:

• Clinical Chemistry
• Hematology
• Public Health Laboratory Science

Background:

• Hemoglobinopathies are a group of inherited blood disorders.
• Accurate and accessible screening methods are crucial for early detection and management.
• Existing methods may be time-consuming or costly for widespread screening.

Purpose of the Study:

• To describe a cost-effective laboratory procedure for screening hemoglobinopathies.
• To evaluate the suitability of filter paper blood specimens for hemoglobin analysis.
• To provide a practical method for public health laboratories.

Main Methods:

• Hemoglobin electrophoresis for initial separation.
• Solubility testing to confirm the presence of sickling hemoglobins.
• Utilized whole blood specimens collected on filter paper for all tests.

Main Results:

• Filter paper blood specimens are satisfactory for both electrophoresis and solubility testing.
• The procedure demonstrated reliability in the first year of screening.
• The method proved to be time-efficient and cost-effective due to filter paper collection.

Conclusions:

• The described procedure is a reliable and practical method for laboratory screening of hemoglobinopathies.
• The use of filter paper simplifies specimen collection and reduces costs, making it ideal for public health initiatives.
• This approach enhances the feasibility of large-scale hemoglobinopathy screening programs.
