Tests starting with the letter Y
Laboratory Test Guide: Tests Starting with the Letter "Y"
A complete list of all tests beginning with the letter "Y" performed at Egemed Hospitals’ Medical Laboratories is provided below. To help our patients understand these tests, a brief medical description and the purpose of each test group are clearly stated.
Microbiology and Culture Tests
Wound Culture
Description: This involves the microbiological culture of a swab sample taken from open wounds, surgical incisions, or infected tissues in a specialized laboratory setting.
Purpose: To identify the specific causative agent of a bacterial or fungal infection that is delaying wound healing and to determine the appropriate antibiotic treatment (based on an antibiogram).
Yersinia Culture (in Stool)
Description: This involves inoculating a stool sample onto specific culture media prepared exclusively for the growth of the "Yersinia enterocolitica" bacterium, which require cold enrichment.
Objective: To diagnose the specific cause of intestinal infections characterized by right lower abdominal pain, fever, and bloody diarrhea, which can be mistaken for appendicitis.
Genetics, Metabolism, and Newborn Screening
NEONATAL METABOLIC SCREENING (COMPREHENSIVE)
Description: This involves screening for dozens of different inherited metabolic and enzyme disorders simultaneously by analyzing a few drops of blood taken from a newborn’s heel using advanced equipment such as tandem mass spectrometry.
Purpose: To detect and treat conditions such as phenylketonuria, biotinidase deficiency, and cystic fibrosis—which can cause intellectual disability or permanent organ damage in infants—at a very early stage before symptoms appear.
Immunology and Allergy Tests
PEANUT (F13) CLIA
Description: This test measures the levels of IgE-class specific allergy antibodies produced by the immune system in response to peanut proteins using the chemiluminescence immunoassay (CLIA) method.
Purpose: To establish a definitive diagnosis of life-threatening peanut allergy—which can cause respiratory arrest or anaphylactic shock even in very small amounts—and to protect the patient.
EGG (F245) CLIA
Description: A comprehensive analysis at the cellular level in the blood of specific IgE antibodies produced by the body in response to whole egg proteins.
Objective: To identify general egg allergy, one of the most common food allergies, particularly in childhood, and to plan a safe diet for the patient.
EGG WHITE (F1) CLIA
Description: This test measures the level of specific IgE antibodies in the laboratory that are produced in response to allergenic proteins found exclusively in the white of an egg (such as ovalbumin, ovomucoid, etc.).
Purpose: To clearly determine which component of the egg causes the allergy and to decide whether certain specific vaccines can be administered (vaccination safety).
EGG YOLK (F75) CLIA
Description: This test measures the specific IgE antibodies produced by the immune system in the bloodstream in response to proteins found exclusively in the yolk of an egg.
Purpose: To prevent cross-reactions in food allergy panels and to determine whether the patient is allergic only to egg white or also to the yolk.
