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 or severe infections
  • ✓Failure to thrive in infancy
  • ✓Family history of immunodeficiency
  • ✓Suspected SCID
  • ✓Evaluation of immune system disorders
  • ✓Genetic counseling for families with immunodeficiency

In plain language

What this test helps you understand

This test helps identify mutations in the RAG1 gene, which are a known cause of severe combined immunodeficiency (SCID), particularly the B cell-negative type. Identifying the specific genetic cause can aid in diagnosis, prognosis, and guiding appropriate medical management.
The RAG1 Gene Severe Combined Immunodeficiency B Cell-Negative NGS Genetic DNA Test is a diagnostic tool used to identify genetic mutations linked to severe combined immunodeficiency (SCID). SCID is a serious condition where the immune system is significantly impaired, increasing susceptibility to infections. This test helps pinpoint the genetic cause of SCID, which can inform treatment and management strategies.

This test specifically looks for changes in the RAG1 gene. This gene plays a vital role in the development of B and T lymphocytes, essential cells for a healthy immune response. By analyzing DNA, the test can detect abnormalities in the RAG1 gene that may lead to immune deficiencies.

Individuals experiencing frequent infections, failure to thrive in infancy, severe allergic reactions, or autoimmune disorders may benefit from this test. It is also recommended for those with a family history of immunodeficiency or known RAG1 gene mutations.

Early diagnosis through this test allows for timely interventions, informed treatment decisions, and access to specialized care. It can also provide valuable information for genetic counseling and family planning.

SampleBlood sample (usually collected in an EDTA tube). Confirm specific requirements with the laboratory before booking.
MethodologyNext-Generation Sequencing (NGS) of the RAG1 gene. Confirm with the laboratory before booking.
PrivacyYour sample and report are handled confidentially. Ask the team how your information is stored and shared.
This test specifically analyzes the RAG1 gene. It may not detect mutations in other genes that can cause SCID or other immunodeficiencies. A negative result does not completely rule out a genetic cause for immunodeficiency. Confirm with the laboratory before booking.

Questions people ask

Frequently asked questions

Severe Combined Immunodeficiency (SCID) is a group of rare, inherited disorders characterized by a severely weakened immune system, making individuals highly vulnerable to infections.
The RAG1 gene provides instructions for making a protein essential for the development of B and T lymphocytes, which are crucial components of the immune system.
Individuals with symptoms like frequent infections, failure to thrive, or a family history of immunodeficiency should discuss testing with their doctor.
A positive result indicates the presence of a mutation in the RAG1 gene, which may be the cause of the patient's immunodeficiency. Further consultation with a healthcare provider is necessary.
Insurance coverage varies. Please check with your insurance provider regarding coverage for this specific genetic test.
