What is Immunodeficiency?

Immunodeficiency is a condition in which the immune system is unable to adequately protect the body against infections, viruses, and diseases. There are two main types:

  • Primary Immunodeficiency: Present from birth, caused by genetic or hereditary defects affecting immune cell development or antibody production, examples include XLA (X-linked agammaglobulinemia) and Severe Combined Immunodeficiency (SCID).
  • Secondary Immunodeficiency: Acquired later in life as a result of illness, medical treatment, or other external factors that suppress or damage the immune system.

At DMV Allergy & Asthma Center, our immunologists specialize in evaluating and managing primary immunodeficiency disorders, working with patients to diagnose the condition, reduce infection risk, and build a long-term immune health plan.

Common Symptoms of Immunodeficiency

The most telling sign of a weakened immune system is frequent, recurrent, or unusually severe infections. Common immunodeficiency symptoms include:

When Should You See an Immunodeficiency Specialist?

Immunodeficiency Testing & Diagnosis

Accurate diagnosis is the essential first step. Our immunologists use a structured evaluation process to identify the type and severity of your immune deficiency.

Medical History & Physical Examination

A detailed review of your infection history, frequency, severity, treatments used, family history of immune disorders, and current medications is the foundation of every immunodeficiency evaluation.

Blood Tests & Immune Cell Count

Comprehensive blood panels measuring white blood cell count, T cell and B cell counts, immunoglobulin levels (IgG, IgA, IgM), and other immune markers to assess the functional capacity of your immune system.

Antibody Testing

Specific antibody tests to evaluate how well your immune system produces and maintains protective antibodies in response to infections or vaccines are a key diagnostic tool for identifying antibody deficiency disorders.

Immunodeficiency Treatment Options

Our immunologists build individualized treatment plans based on the type and severity of your immune disorder, focused on reducing infections, supporting immune function, and improving quality of life.

Antibiotic Therapy

For patients with primary immunodeficiency, carefully managed antibiotic regimens are used to treat active infections and, in some cases, prescribed on a preventive basis to reduce the risk of recurring bacterial infections.

Antibody Replacement Therapy

For patients with antibody deficiency disorders, regular antibody (immunoglobulin) replacement therapy helps restore protective antibody levels, significantly reducing the frequency and severity of infections.

Ongoing Immune Monitoring & Management

Regular follow-up at our Alexandria, VA, K Street, DC, Foxhall, DC, and Frederick, MD clinics to monitor immune markers, track infection frequency, and adjust the treatment plan as your condition changes over time.

Asthma Testing & Diagnosis

Diagnosing asthma accurately means looking at two things: how your lungs are actually functioning, and what is triggering the inflammation driving your symptoms. Our board-certified asthma specialists use a targeted combination of lung function testing and allergy diagnostics to get the full picture, so your treatment plan attacks the problem from every angle.

Pulmonary Function Testing (PFT / Spirometry)

The gold-standard test for asthma diagnosis. Measures how much air you can inhale and exhale, and how fast, giving us a precise picture of your lung function and confirming whether airflow obstruction is present. Performed in-office at all our locations.

Skin Prick Testing

For allergic asthma, identifying the exact allergens driving your airway inflammation is critical. Skin prick testing delivers clear, actionable results in approximately 20 minutes, covering pollen, dust mites, pet dander, mold, and more.

Blood Testing & Allergen Panel

Measures allergen-specific IgE levels in the blood to detect immune-driven asthma triggers, particularly useful when skin testing is not suitable or when a deeper immune system profile is needed.

Skin Prick Testing

Quick, accurate results in about 20 minutes

Asthma Treatment Options

We treat all four major types of asthma, allergic, exercise-induced, cough-variant, and occupational, with evidence-based therapies tailored to each patient.

Rescue & Controller Medications

Short-acting bronchodilators for immediate relief and long-term controller medications, including inhaled corticosteroids and combination inhalers, are prescribed and monitored by our asthma specialists.

Allergy Immunotherapy

When allergic triggers drive your asthma, allergy shots gradually reduce your immune system's sensitivity, decreasing both allergy and asthma symptoms over time.

Biologic Therapy

For moderate-to-severe allergic asthma that doesn't respond to standard medications, biologic treatments target specific immune pathways, significantly reducing asthma attacks and improving lung function.

Asthma Action Plans & Education

Every patient leaves with a written personalized asthma action plan and practical education on inhaler technique, trigger avoidance, and what to do during a flare-up or emergency.

So far, so great! I’ve been a patient of Dr. Nataraj’s for about a month, and I’ve already experienced improvement with my issues. Thank you to him and the amazing staff…nurses, front desk, immunotherapy group, etc. I look forward to my continued treatment and healing!

Le docteur Fishman m'a vraiment beaucoup aidé avec mon asthme. Quand je l'ai consulté pour la première fois, je gérais très mal mon asthme. Maintenant, je respire normalement. Je recommande vivement le docteur Fishman.

Frequently Asked Questions

Immunodeficiency is a condition where the immune system cannot adequately defend the body against infections and illness. It can be primary (present from birth due to genetic causes) or secondary (acquired later in life due to illness or other factors).
The most common signs are frequent, recurrent, or unusually severe infections, such as 4 or more sinus or respiratory infections per year, repeated pneumonia, infections that don’t respond to antibiotics, or chronic skin infections. Digestive problems and a family history of immune disorders are also warning signs.
Diagnosis begins with a detailed medical history and physical examination, followed by blood tests to measure immune cell counts, immunoglobulin levels, and antibody function. These tests help our immunologists identify the specific type and severity of the immune disorder.
Treatment depends on the type of immunodeficiency. Common approaches at DMV Allergy & Asthma Center include antibiotic therapy to treat and prevent infections, and antibody replacement therapy for patients with antibody deficiency disorders. Every patient receives an individualized plan with ongoing monitoring.
Yes, primary immunodeficiency disorders are often identified in childhood, as children with these conditions typically experience an unusual number or severity of infections from an early age. Early evaluation and diagnosis are essential to protect a child’s long-term health and development.
