About this service

The cystic fibrosis test is considered a vital step in diagnosing cystic fibrosis. This hereditary disease primarily affects the mucus-secreting glands, leading to the accumulation of thick mucus in the lungs and other organs, which can cause serious respiratory and digestive problems. This test is based on analyzing genetic mutations associated with the disease, helping to identify individuals who carry the causative gene. It is recommended for children who show symptoms such as chronic cough, difficulty breathing, or poor growth. Through this test, physicians can develop an appropriate treatment plan to improve patients’ quality of life.

Purpose Test

Genetic mutations: Identifies mutations in the CFTR gene associated with cystic fibrosis.
Respiratory function: Assesses the impact of the disease on the lungs and respiratory system.
Pancreatic function: Reveals the effect of the disease on the production of digestive enzymes.
Sweat chloride levels: High levels of salt in sweat may indicate the presence of the disease.

Recommended groups

Children: Who show symptoms such as chronic cough, shortness of breath, or poor growth.
Individuals with a family history of cystic fibrosis: To help determine potential genetic risk.
Individuals with abnormal results in other tests: Such as sweat tests or respiratory assessments.
Newborns: As part of newborn screening in some countries for early detection of the disease.

Symptoms indicative

Chronic cough: Especially if accompanied by thick mucus.
Shortness of breath: Or difficulty breathing.
Recurrent lung infections: Such as pneumonia.
Digestive problems: Such as poor nutrient absorption or fatty diarrhea.
Poor growth: Or unexplained weight loss in children.
Excessive sweating: Especially in hot weather.

Normal Levels

Sweat test: Chloride levels in sweat below 30 mmol/L are considered normal. Levels between 30 and 60 mmol/L are considered a borderline range, while levels above 60 mmol/L often indicate a possible presence of cystic fibrosis.
Genetic tests: Absence of known mutations in the CFTR gene is considered a normal result.
Lung function tests: Values vary by age and gender, but generally, normal airflow measurement is a good indicator.
