Laboratory diagnosis for thalassemia.

Area of Science:

• Medical Genetics
• Hematology

Background:

• Thalassemia is a prevalent global genetic blood disorder.
• Common mutations in Southeast Asia include alpha-thalassemia, beta-thalassemia, Hb E, and Hb Constant Spring.
• Accurate diagnosis is vital for identifying at-risk couples requiring prenatal diagnosis.

Purpose of the Study:

• To review laboratory methods and strategies for diagnosing thalassemia and common abnormal hemoglobin carriers in Southeast Asia.
• To highlight the importance of diagnostic accuracy for genetic counseling and prenatal screening.

Main Methods:

• Review of existing literature on laboratory diagnostic techniques.
• Analysis of methods for detecting various thalassemia types and hemoglobin variants.
• Discussion of challenges in diagnosing carrier states.

Main Results:

• Clinical findings, hematologic data, and hemoglobin electrophoresis are effective for diagnosing severe thalassemic diseases.
• Diagnosing thalassemia carriers often requires advanced techniques like in vitro protein synthesis and DNA analysis.
• A range of laboratory methods are available, varying in complexity and application.

Conclusions:

• Effective laboratory strategies are essential for the diagnosis of thalassemia and abnormal hemoglobin disorders.
• Distinguishing between symptomatic disease and carrier states requires tailored diagnostic approaches.
• Continued development and application of sophisticated techniques are necessary for comprehensive carrier screening.
