In the past nucleic acid tests have mainly been used as a secondary test to confirm positive serological results. [3] However, as they become cheaper and more automated, they are increasingly becoming the primary tool for diagnostics and can also be use for monitoring of treatment of viral infected individuals t.
Liver function tests (LFTs or LFs), also referred to as a hepatic panel or liver panel, are groups of blood tests that provide information about the state of a patient's liver. [1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin , bilirubin (direct and indirect), and others.
Transformation infections is limited to abortive or restrictive infections. [1] This constitutes the broadest category of infections as it can include both cytocidal and persistent infection. Viral transformation is most commonly understood as transforming infections, so the remainder of the article focuses on detailing transforming infections.
Viral hepatitis is liver inflammation due to a viral infection. [ 1 ] [ 2 ] It may present in acute form as a recent infection with relatively rapid onset, or in chronic form, typically progressing from a long-lasting asymptomatic condition up to a decompensated hepatic disease and hepatocellular carcinoma (HCC).
Non-invasive tests for liver fibrosis in alcoholic, nonalcoholic and viral liver diseases are likely to become more widely used. [ 2 ] If the diagnosis is already clear, such as chronic hepatitis B or hepatitis C , liver biopsy is useful to assess the severity of the associated liver damage.
Viral infections may have clinically relevant phenotypical CPEs. For example, with the hepatitis C virus (HCV), liver steatosis is characteristic enough of the virus that it may be used to help identify the genotype , the genetic composition of the virus.
Viral culture is a laboratory technique [1] in which samples of a virus are placed to different cell lines which the virus being tested for its ability to infect. If the cells show changes, known as cytopathic effects , then the culture is positive.
It produces test results in 5 minutes using its ID NOW portable testing system. [1] It also received EUA for its m2000-based laboratory nucleic acid test for COVID-19. [2] In April 2020, Abbott received EUA for its ARCHITECT IgG laboratory antibody test for COVID-19. [3] Also in April, Abbott's ID NOW test was reported to have sensitivity of 85 ...
