01

Start with fit

Is this the right test for you?

The best test starts with a clear clinical question. These are common reasons a clinician or family may consider this test.

  • ✓Recurrent bacterial or fungal infections
  • ✓Family history of chronic granulomatous disease (CGD)
  • ✓Symptoms suggestive of CGD, such as granuloma formation
  • ✓Diagnosis confirmation for suspected CGD cases
  • ✓Carrier screening in affected families

In plain language

What this test helps you understand

This test helps confirm a diagnosis of X-linked CGD, identify the specific genetic mutation causing the condition, and inform treatment decisions. It can also be used for carrier screening in families with a history of CGD.
The CYBB Gene Granulomatous Disease Chronic Xlinked NGS Genetic DNA Test is a diagnostic tool used to identify mutations in the CYBB gene. This gene is linked to X-linked chronic granulomatous disease (CGD), a condition affecting the immune system and increasing susceptibility to infections.

This test utilizes advanced Next Generation Sequencing (NGS) technology for a comprehensive analysis of the CYBB gene. Identifying specific genetic mutations helps healthcare providers understand the cause of CGD in patients and develop appropriate management strategies.

This test measures mutations within the CYBB gene, which provides instructions for making a part of the NADPH oxidase complex. This complex is vital for immune cells to produce substances that kill certain bacteria and fungi. Mutations can impair this function, leading to CGD.

MethodologyNext Generation Sequencing (NGS) is used to analyze the CYBB gene for mutations.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test specifically analyzes the CYBB gene. It may not detect mutations in other genes associated with CGD. Results should be interpreted in the context of clinical findings and family history. Confirm with the laboratory before booking.

What common result terms mean

PositiveA finding was identified. Your clinician or counselor will explain what it means for your care.
NegativeThe specific finding tested for was not identified. It does not rule out every possible cause.
VUSA variant was found, but current evidence is not enough to classify it. Your counselor can explain follow-up.

Questions people ask

Frequently asked questions

CGD is a genetic disorder affecting the immune system, making individuals more prone to severe infections caused by bacteria and fungi.
This test looks for mutations (changes) in the CYBB gene, which is the most common cause of X-linked CGD.
Individuals with recurrent infections, a family history of CGD, or symptoms like granulomas should discuss this test with their doctor.
A sample can be collected as a blood draw, extracted DNA, or a single drop of blood on a special card.
Your doctor will discuss the results with you. Genetic counseling is often recommended to help understand the implications.
