LFT

LFT is an acronym with multiple meanings, most commonly encountered in medical and diagnostic contexts. The exact meaning depends on the field and the surrounding information.

Liver Function Tests (LFTs) are a group of blood tests used to assess liver health. They typically measure enzymes such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyltransferase (GGT), as well as bilirubin, albumin, and coagulation parameters like prothrombin time. Abnormal results can indicate liver inflammation, damage, bile duct obstruction, or chronic liver disease, but they do not specify a diagnosis. Interpretation relies on patterns and clinical context, and repeat testing or additional imaging and investigations may be required.

Lateral Flow Test (LFT) is a rapid diagnostic method based on immunochromatography. A liquid sample moves along a strip by capillary action, encountering labeled antibodies that bind target substances. If present, the labeled complexes are captured on a test line, yielding a visible signal. LFTs are widely used for point-of-care testing, including home pregnancy tests and rapid antigen tests for infections such as SARS-CoV-2, influenza, or malaria. They are generally quick and easy to use but vary in sensitivity and specificity, and negative results may not rule out infection in early or low-load cases.

Other uses of the acronym exist in various technical fields, but Liver Function Tests and Lateral Flow Tests are the most common meanings in medical and diagnostic contexts. Context usually clarifies the intended meaning.
