PHENOLTETRACHLORPHTHALEIN TEST Meaning and
Definition
-
The phenoltetrachlorphthalein test is a chemical test used in the medical field to assess the function of the liver and its ability to excrete bile. Also known as the "PTC test" or the "Bilirubin on Blood" test, it is based on the reaction between phenoltetrachlorphthalein (a dye) and bilirubin (a yellow pigment produced during the breakdown of old red blood cells).
In this test, a small sample of blood is collected from the patient and mixed with the phenoltetrachlorphthalein compound. The rate at which the dye disappears from the blood sample is an indication of the liver's ability to excrete bilirubin. Functioning properly, the liver continuously eliminates bilirubin from the body by secreting it into bile, which is then excreted into the intestines.
A rapid disappearance of the dye from the blood indicates normal liver function, as it suggests efficient excretion of bilirubin. On the other hand, delayed or incomplete disappearance of the dye suggests impaired liver function, indicating possible liver disease or other conditions affecting bile excretion.
The phenoltetrachlorphthalein test is valuable in the diagnosis and monitoring of various liver disorders, such as hepatitis, cirrhosis, and cholestasis. By evaluating the rate at which the dye is cleared from the blood, healthcare professionals can assess the liver's ability to perform its essential functions, aiding in prompt and accurate diagnosis and treatment.
-
A test of the functional activity of the liver; the dye in a specially prepared solution is injected intravenously, and the stools are then collected for 48 hours and the urine for 24, and examined to determine the amount of the dye excreted; a diminution of the amount normally recovered from the feces offers a presumption of disease of the liver.

Etymology of PHENOLTETRACHLORPHTHALEIN TEST
The etymology of the word "phenoltetrachlorphthalein test" can be broken down as follows:
1. Phenol: This term comes from the Greek word "phaino", which means "to show" or "to appear". Phenol is an organic compound that often appears as a white crystalline solid and is used in a variety of chemical processes.
