Method Verification of the Caretium XC-A30 Automated Erythrocyte Sedimentation Rate Analyser for Erythrocyte Sedimentation Rate.

Background: The erythrocyte sedimentation rate (ESR) analyser is widely used in haematological testing. In addition to the Westergren method, new automatic methods for ESR measurements have been developed. We aimed to study the reliability, precision, accuracy and stability of the Caretium XC-A30 automated ESR analyser.

Prenatal diagnosis of α- and β-thalassemias in southern Thailand.

We report our work on prenatal diagnosis of α-thalassemia, β-thalassemia and other hemoglobinopathies in southern Thailand. DNA-based diagnosis was offered to 1906 pregnancies at risk for thalassemia using a combination method of multiplex-PCR and reverse dot blot analysis to detect seven α-globin and 47 β-globin mutations. The most commonly detected mutation of α-thalassemia was a South-East Asian deletion (98%), followed by a Thai deletion (2%).

Molecular basis and hematological features of hemoglobin variants in Southern Thailand.

Hemoglobinopathy (abnormal hemoglobin or hemoglobin variant) is an inherited disorder that results in the abnormal structure of globin chains of the hemoglobin (Hb) molecule. Many abnormal Hbs have been characterized worldwide, including more than 20 variants in Thailand. The Bio-Rad Variant II HPLC system is used for investigating hemoglobin variants at Songklanagarind Hospital.
