Laboratory Diagnosis of Tuberculosis - Latest Diagnostic Tools
نویسنده
چکیده
Microscopy has been a diagnostic tool for TB for over a century, and still currently the most rapid diagnostic method. Standard light microscopy (LM) and fluorescent microscopy (FM) are common methods. The recent development of light emitting diodes (LED), with the ap‐ propriate fluorescent light output for FM and low power consumption, has led to the devel‐ opment of simple, robust LED FM microscopes, requiring minimal mains or battery power and no dark room requirement. The WHO has recommended rolling it out as an alternative to LMs in resource-limited settings, based on studies that have shown comparable perform‐ ance of LM and standard FM systems [4,5].

Peripheral Lymphadenopathy: Approach and Diagnostic Tools
Peripheral lymph nodes, located deep in the subcutaneous tissue, clean antigens from the extracellular fluid. Generally, a normal sized lymph node is less than one cm in diameter. Peripheral lymphadenopathy (LAP) is frequently due to a local or systemic, benign, self-limited, infectious disease. However, it could be a manifestation of underlying malignancy. Seventy-five percent of all LAPs are ...

متن کاملDiagnosis of Pulmonary Tuberculosis Using Artificial Intelligence (Naive Bayes Algorithm)
Background and Aim: Despite the implementation of effective preventive and therapeutic programs, no significant success has been achieved in the reduction of tuberculosis. One of the reasons is the delay in diagnosis. Therefore, the creation of a diagnostic aid system can help to diagnose early Tuberculosis. The purpose of this research was to evaluate the role of the Naive Bayes algorithm as a...
متن کاملLaboratory Diagnosis of Mycobacterium tuberculosis Infection and Disease in Children.
Diagnosis of tuberculosis in children is challenging; even with advanced technologies, the diagnosis is often difficult to confirm microbiologically in part due to the paucibacillary nature of the disease. Clinical diagnosis lacks standardization, and traditional and molecular microbiologic methods lack sensitivity, particularly in children. Immunodiagnostic tests may improve sensitivity, but t...
متن کاملDiagnosis of Tuberculosis: Novel Laboratory Methods
Despite advances in medical sciences in recent years, tuberculosis remains a worldwide health problem. Although there are many laboratory methods to accelerate the diagnosis, a delay in the definitive diagnosis of the disease is still a major clinical problem. Due to the slow growth of the causative agent, (Mycobacterium tuberculosis), isolation, identification, and other clinically important m...
