Allergy & Asthma Center in Baltimore: Testing, Treatment, and Immunotherapy Under One Roof

The Allergy & Asthma Center is an independent allergist practice in Baltimore that diagnoses and treats allergic diseases and asthma in both adults and children, with an emphasis on allergy testing and customized immunotherapy. It operates as a medical practice distinct from hospital-based allergy programs, giving patients a direct relationship with the treating allergist rather than rotating through residents or fellows.

What the practice actually does

The center handles the full diagnostic spectrum: skin-prick testing and intradermal testing to identify specific allergens, blood testing (specific IgE) when skin testing is contraindicated or inconclusive, spirometry and methacholine challenges for asthma evaluation, and comprehensive history and physical exam. Once allergen sensitivity is identified, the practice prescribes and administers immunotherapy, which trains the immune system to tolerate allergens over 3 to 5 years through either subcutaneous (allergy shot) or sublingual (under-the-tongue tablet) protocols.

Services and cost structure

Allergy skin testing costs $150 to $300 depending on the number of allergens tested, and results appear within 15 to 20 minutes on the same visit. Intradermal testing, used when skin-prick results are borderline, typically costs an additional $100 to $150. Specific IgE blood tests (RAST) usually cost $200 to $400 per panel depending on how many allergens are screened.

Immunotherapy pricing depends on the protocol. Subcutaneous immunotherapy (allergy shots) given in-office typically involves a build-up phase of weekly or biweekly injections over 4 to 6 months, then a maintenance phase of monthly injections. Most practices charge $40 to $80 per injection; ask whether the initial vial/serum is included in the per-injection cost or billed separately, as some centers add a $100 to $200 serum preparation fee. Sublingual immunotherapy (tablets for dust mite, ragweed, or grass) avoids office visits and costs $50 to $150 monthly under insurance, though cash pricing varies. Verify current copays and deductible structure with your insurance before scheduling.

Consultation visits (intake and testing plan) range from $150 to $300; established-patient visits with immunotherapy administration or follow-up are often $75 to $150. Insurance coverage is standard for diagnosed allergic rhinitis, asthma, and food allergy; check whether your plan requires a referral from your primary care doctor before the first visit.

How this practice compares to other Baltimore-area allergists

Allergy & Asthma Center is one of the few independent allergist offices in central Baltimore; most competing options are pulmonologists who add allergy care, dermatologists offering patch testing for contact dermatitis, or allergists embedded within large medical systems like the UM Allergy & Immunology Department at UMMC or Sinai Hospital. Independent practices typically offer more flexible scheduling, same-day testing results, and a continuity relationship with one or two familiar providers. Hospital-based allergy services excel at managing complex asthma, particularly severe or eosinophilic asthma requiring biologic therapy (monoclonal antibodies such as dupilumab or mepolizumab), which requires rheumatology-level monitoring and is often unavailable in small office practices. If your allergies are straightforward and you value convenience and personal continuity, Allergy & Asthma Center is a practical choice. If you have moderate-to-severe asthma or multisystem allergic disease (eczema, food allergy, anaphylaxis history), a hospital-based practice with allergy specialists and backup systems for severe reactions may be safer.

Who it serves and who should look elsewhere

This center is ideal for adults and children with isolated allergic rhinitis (seasonal or year-round), mild-to-moderate asthma controlled by standard inhalers, or a single food or environmental allergy requiring confirmation. It also suits people who have already been diagnosed by another provider but want a dedicated allergist for long-term immunotherapy without the wait times of large medical centers.

Patients with anaphylaxis history, severe persistent asthma, atopic dermatitis requiring systemic therapy, or suspected occupational allergies may be better served by a hospital-based or academic allergist with access to biologic therapy, oral immunotherapy programs, and multidisciplinary support.

First visit: what to bring and how long it takes

Arrive with a list of allergen exposures that trigger symptoms (pets, pollens, molds, foods) and the season or pattern (year-round, spring only, after eating tree nuts). Bring your current medications and inhalers. The intake appointment lasts 30 to 45 minutes and includes a history, physical, and often immediate allergy skin testing. You will not need fasting or sedation. After testing, the allergist reviews results and discusses an immunotherapy plan on the same day if indicated.

Hours, parking, and practical details

Confirm hours before visiting, as office allergist hours often do not match hospital clinic schedules. Parking is available on-site or on the street in the surrounding Baltimore neighborhood; call ahead to confirm lot access. Most offices require 24 hours notice to cancel testing appointments to avoid a no-show fee.

This practice fills a straightforward diagnostic and management role in Baltimore's medical landscape, suitable for patients who want rapid allergy testing and immunotherapy without the bureaucracy of larger systems.
