Leukemia/Leukaemia: An Overview of Introduction, Types, Pathogenesis,Lab Diagnosis, Treatment, Prevention, and Keynotes

Introduction Leukemia (also spelled leukaemia) is a group of malignant hematological cancers originating in the bone marrow, characterized by the rapid, uncontrolled proliferation of abnormal, non-functional white blood cells (leukocytes). As these malignant cells accumulate, they crowd out healthy red blood cells, functional white blood …

Mini-Centrifuge-Introduction, Principle, Handling Procedure, Application, and Keynotes

This image shows a compact benchtop mini-centrifuge with a clear dome lid, designed for quick spin-downs of laboratory microtubes.

Introduction Also known as a microcentrifuge, this compact tool is a staple in biological, clinical, and molecular laboratories. Unlike massive, refrigerated floor models, mini-centrifuges are designed for quick spins. They typically accommodate 0.2 mL to 2.0 mL microcentrifuge tubes and feature fixed-angle rotors that reach …

Xpert MTB-XDR: Introduction, Principle, Procedure, Result-Interpretation, Uses, and Keynotes

The image shows a GeneXpert software interface displaying an Xpert MTB/XDR test result with M. tuberculosis (MTB) detected and a specific drug resistance profile.Key Findings:MTB DETECTED: Positive for Mycobacterium tuberculosis complex.Low FLQ Resistance DETECTED: Indicates low-level resistance to fluoroquinolones (e.g., levofloxacin or moxifloxacin).Resistance NOT DETECTED: No mutations were found for isoniazid (INH), amikacin (AMK), kanamycin (KAN), capreomycin (CAP), or ethionamide (ETH).This result is consistent with a pre-XDR-TB diagnosis, as there is resistance to fluoroquinolones but susceptibility to second-line injectables.

Introduction The Xpert MTB/XDR assay is an advanced molecular diagnostic tool designed by Cepheid to rapidly detect Mycobacterium tuberculosis complex (MTBC) and its resistance to multiple first- and second-line drugs. Launched in 2021, it is categorized as a “low complexity” automated nucleic acid amplification test …
