    Rapid advice: diagnosis, prevention and management of cryptococcal disease in HIV-infected adults, adolescents and children

    Increasing access to antiretroviral therapy (ART) has transformed the prognosis of HIVinfected patients in resource-limited settings (RLS). However, treatment coverage remains relatively low, and HIV diagnosis occurs at a late stage. As a result, many patients continue to die of HIV-related opportunistic...

    Commercial serodiagnostic tests for diagnosis of tuberculosis: policy statement

    An antibody detection-based diagnostic test in a user-friendly format could potentially replace microscopy and extend tuberculosis diagnosis to lower levels of health services. Dozens of commercial serological tests for tuberculosis are being marketed in many parts of the world, despite previous systemat...

    Guideline on HIV disclosure counselling for children up to 12 years of age

    The World Health Organization (WHO) has developed guidance for health care workers on how to support children up to 12 years of age and their caregivers with disclosure of HIV status. Health care workers (HCWs) know that disclosure decisions are complex because of stigma, social support concerns, family ...

    Fluorescent light-emitting diode (‎LED)‎ microscopy for diagnosis of tuberculosis: policy statement

    Conventional light microscopy of Ziehl-Neelsen-stained smears prepared directly from sputum specimens is the most widely available test for diagnosis of tuberculosis (TB) in resource-limited settings. Ziehl-Neelsen microscopy is highly specific, but its sensitivity is variable (20–80%) and is significa...

    Use of tuberculosis interferon-gamma release assays (‎IGRAs)‎ in low- and middle-income countries: policy statement

    Research over the past decade has resulted in the development of two commercial interferongamma release assays (IGRAs), based on the principle that the T-cells of individuals who have acquired TB infection respond to re-stimulation with Mycobacterium tuberculosis-specific antigens by secreting interferon...

    Policy statement: automated real-time nucleic acid amplification technology for rapid and simultaneous detection of tuberculosis and rifampicin resistance: Xpert MTB/RIF system

    Earlier and improved tuberculosis (TB) case detection - including smear-negative disease, often associated with HIV co-infection - as well as expanded capacity to diagnose multidrug-resistant tuberculosis (MDR-TB) are global priorities for TB control. Conventional laboratory methods are slow and cumberso...

    Same-day diagnosis of tuberculosis by microscopy: policy statement

    Direct sputum smear microscopy is the most widely used means for the diagnosis of pulmonary tuberculosis (TB) and is available in most primary health-care laboratories at health-centre level. Smear microscopy may, however, be costly and inconvenient for patients, who have to make multiple visits to healt...

    Use of Glycated Haemoglobin (HbA1c) in the Diagnosis of Diabetes Mellitus Abbreviated Report of a WHO Consultation

    This report is an addendum to the diagnostic criteria published in the 2006 WHO/IDF report “Definition and diagnosis of diabetes mellitus and intermediate hyperglycaemia” , and addresses the use of HbA1c in diagnosing diabetes mellitus. The WHO Consultation concluded that HbA1c can be used as a diag...

    Delirium: prevention, diagnosis and management

    This guideline covers diagnosing and treating delirium in people aged 18 and over in hospital and in long-term residential care or a nursing home. It also covers identifying people at risk of developing delirium in these settings and preventing onset. It aims to improve diagnosis of delirium and reduce h...

    WHO recommendations on the management of diarrhoea and pneumonia in HIV-infected infants and children

    To improve survival and quality of life among the 2.5 million children living with HIV, a comprehensive package of prevention, care and treatment is required. This package should include management of infections such as pneumonia, diarrhoea, malaria and ear infections, as well as common opportunistic inf...
