Para-Bombay blood group: Report of a rare blood group.

Para-Bombay blood group is a rare blood group typically characterized by the absence of H antigens on red blood cell and the presence of ABH substances on secretion. It can be easily missed and often mistaken as blood group O without extended testing. Detection is important as it significantly affect transfusion management.

A Favourable Outcome in a Congenital Leukaemia Patient With Unique Cytogenetic Abnormalities.

Congenital leukaemia (CL) is an exceptionally uncommon hematologic malignancy originating intrauterine and is typically associated with an unfavourable prognosis. The present case is a seven-day-old Malay baby girl who presented with mild fever and hepatosplenomegaly. She was initially treated as neonatal sepsis however subsequent investigations with bone marrow, trephine biopsy and immunophenotyping were consistent with B acute lymphoblastic leukaemia.

The Importance of Molecular Biological Analysis for the Laboratory Diagnostic of Homozygous Haemoglobin Malay.

Haemoglobin (Hb) Malay is variant haemoglobin with a β thalassemia phenotype. The prevalence of Hb Malay in the Malaysian population was 5.5%.

A rare case of compound heterozygous Southeast Asian double α-globin gene deletion and Haemoglobin Quong Sze in a Malay proband.

Introduction: Haemoglobin (Hb) Quong Sze is a non-deletional α-thalassaemia subtype that occurs due to missense mutation at codon 125 of the HBA2 gene. Interaction between Hb QS with Southeast Asian double α-globin gene deletion results in non-deletional HbH disease, which is more severe than deletional HbH.

Case Report: A 3-month-old baby boy was presented with neonatal anaemia and mild hepatomegaly.

Clinical and Laboratory Diagnosis of Antiphospholipid Syndrome: A Review.

The antiphospholipid syndrome (APS) manifests through venous or arterial thrombosis, with or without pregnancy complication alongside the continuous presence of antiphospholipid antibodies (aPL). APS classification relies on three aPL subtypes: anticardiolipin (aCL), anti-β2-glycoprotein I antibodies (anti-β2GPI), and lupus anticoagulants (LA) antibodies. Given that thrombosis and pregnancy issues are not unique to APS, the precise and reliable identification of aPL forms the basis for diagnosis.
