Report aims to identify list of critically required diagnostic tests.
Recently, the World Health Organization published its first Essential Diagnostics List, a catalogue of the tests needed to diagnose the most common conditions as well as a number of global priority diseases.
Today, many people are unable to get tested for diseases because they cannot access diagnostic services. Many are incorrectly diagnosed. As a result, they do not receive the treatment they need and, in some cases, may actually receive the wrong treatment.
For example, an estimated 46% of adults with Type 2 diabetes worldwide are undiagnosed, risking serious health complications and higher health costs. Late diagnosis of infectious diseases such as HIV and tuberculosis increases the risk of spread and makes them more difficult to treat.
“An accurate diagnosis is the first step to getting effective treatment,” says Dr Tedros Adhanom Ghebreyesus, WHO Director-General. “No one should suffer or die because of a lack of diagnostic services, or because the right tests were not available.”
The list concentrates on in vitro tests - i.e. tests of human specimens like blood and urine. It contains 113 products: 58 tests are listed for detection and diagnosis of a wide range of common conditions, providing an essential package that can form the basis for screening and management of patients. The remaining 55 tests are designed for the detection, diagnosis and monitoring of “priority” diseases such as HIV, tuberculosis, malaria, hepatitis B and C, human papillomavirus and syphilis.
For each category of test, the Essential Diagnostics List specifies the type of test and intended use, format, and if appropriate for primary health care or for health facilities with laboratories. The list also provides links to WHO Guidelines or publications and, when available, to prequalified products.
