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.
