Cystic Fibrosis (CF) Delta F508 Mutation Analysis

Cystic Fibrosis (CF) Delta F508 Mutation Analysis identifies the specific Delta F508 mutation associated with cystic fibrosis. This mutation disrupts the normal function of the CFTR protein, impacting salt and water balance in cells. Understanding this mutation helps diagnose and manage cystic fibrosis.

This test is done to:

• Confirm a diagnosis of cystic fibrosis
• Assess carrier status for at-risk individuals
• Aid in family planning decisions for couples with a family history of cystic fibrosis
• Guide treatment decisions for individuals with cystic fibrosis

This test is often recommended if you:

• Have symptoms suggestive of cystic fibrosis (e.g., chronic cough, recurrent lung infections)
• Have a family history of cystic fibrosis or are planning a pregnancy
• Need to confirm a diagnosis or assess prognosis for cystic fibrosis

Abnormal results indicate the presence of the Delta F508 mutation and an increased risk of developing cystic fibrosis or being a carrier. Further testing may be needed for confirmation.

During the test:

• A small blood or saliva sample will be collected for analysis.
• The sample will be sent to the laboratory for genetic testing.
• You may experience mild discomfort during sample collection.

Before the test:

• No specific preparations are needed for this genetic test.
• You may eat and drink normally before providing a blood or saliva sample.
• Follow any instructions given by your healthcare provider.

• Sweat Chloride Test: Measures the amount of salt in sweat to diagnose cystic fibrosis.
• Pulmonary Function Tests: Evaluate lung function in individuals with cystic fibrosis.

CF Genetic Testing or CFTR Gene Mutation Analysis

Cystic fibrosis is a genetic disorder that primarily affects the lungs and digestive system. It leads to the production of thick, sticky mucus that can obstruct airways and impair digestion, causing respiratory and digestive issues.
