FIGLU TESTS Meaning and
Definition
-
FIGLU tests, also known as formiminoglutamic aciduria tests, are laboratory procedures used to identify and measure the levels of formiminoglutamic acid (FIGLU) in urine. Formiminoglutamic acid is an intermediate compound formed during the breakdown of histidine, an essential amino acid, in the body.
These tests are primarily used to diagnose a rare genetic disorder called formiminoglutamic aciduria or formiminotransferase deficiency. In individuals with this disorder, a specific enzyme called formiminotransferase is either absent or deficient, leading to the accumulation of FIGLU in the body. This build-up is harmful and can cause various health problems.
To perform a FIGLU test, a urine sample is collected from the patient and sent to a laboratory for analysis. The sample is processed, and the concentration of FIGLU is measured using techniques like spectrophotometry or liquid chromatography. The results are then compared to the normal range, and abnormalities in FIGLU levels can indicate the presence of formiminoglutamic aciduria.
A positive FIGLU test suggests the possibility of formiminoglutamic aciduria, but further investigations and genetic testing may be required to confirm the diagnosis. Early detection of this disorder is crucial as prompt treatment and management can help prevent potential complications and improve the patient's overall quality of life.
In summary, FIGLU tests are diagnostic procedures used to assess the levels of formiminoglutamic acid in urine, aiding in the detection of formiminoglutamic aciduria or formiminotransferase deficiency, a rare genetic disorder affecting histidine metabolism.

Etymology of FIGLU TESTS
The term "FIGLU tests" stands for "Formiminoglutamic aciduria" tests. Its etymology can be broken down as follows:
1. Formiminoglutamic aciduria (FIGLU): This is a metabolic disorder characterized by the inability to convert the amino acid histidine into glutamic acid due to a deficiency in the enzyme formiminotransferase cyclodeaminase. As a result, an intermediate metabolite called formiminoglutamic acid (FIGLU) accumulates in the body, leading to various health issues. The term FIGLU was derived by combining the names of its constituent molecules, "formimino" and "glutamic acid".
2. Tests: In this context, "tests" simply refers to the diagnostic processes used to detect or measure the levels of FIGLU in a patient's urine or blood. These tests involve biochemical analysis techniques.
