Viruses are often isolated from the initial patient sample. This allows the virus sample to be grown into larger quantities and allows a larger number of tests to be run on them. This is particularly important for samples that contain new or rare viruses for which diagnostic tests are not yet developed. [citation needed]

A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment. The tests are classified by speciality field, conveying in which ward of a hospital or by which specialist doctor these tests are usually performed.
Some tests such as a quick test for malaria, do not require a laboratory, a health care setting or professional, or electricity. [10] For each group of tests, the EDL specifies the test's name, purpose, assay format and type of specimen. [6] Supporting WHO Guidelines or publications are linked and brands are not referenced.

Virus classification showing major ranks This is a list of genera of biological viruses. See also Comparison of computer viruses. This is an alphabetical list of genera of biological viruses. It includes all genera and subgenera of viruses listed by the International Committee on Taxonomy of Viruses (ICTV) 2022 release. [1]
Viruses infect all life forms; therefore the bacterial, plant, and animal cells and material in the gut also carry viruses. [6] When viruses cause harm by infecting the cells in the body, a symptomatic disease may develop. Contrary to common belief, harmful viruses may be in the minority, compared to benign viruses in the human body.
