What an allergist does — and which parts an online service can do

Not entirely, and it should not claim to. For an uncomplicated environmental allergy — pollen, dust mites, mold, pet dander — a remote service can cover the functions that matter: identifying which allergens you are sensitized to via blood IgE testing, having a licensed allergy clinician review results and prescribe, adjusting the protocol over time, and monitoring progress. What it cannot do is skin-prick testing, lung-function testing, evaluation of a suspected food or drug allergy, or management of an acute reaction. Those require an in-person allergist.

Licensed clinicians, and Curex names them publicly rather than describing an anonymous "medical team". Its clinical advisors include Dr. Neeta Ogden, MD, FAAAAI — board-certified in allergy and immunology, a fellow of both the American Academy of Allergy, Asthma & Immunology and the American College of Allergy, Asthma & Immunology — and Dr. Payel Gupta, MD, FACAAI, triple board-certified in internal medicine, pediatrics, and allergy and immunology. Dr. Chet Tharpe, MD, is the medical reviewer and the lead author of the published outcome study. Being able to check who stands behind the clinical decisions is a reasonable thing to require of any health service.

There has to be a doctor, and that is a legal requirement rather than a company promise. In the US, prescribing is a medical act: the clinician must hold a licence in the state where the patient is located, and a valid clinician–patient relationship must be established before any prescription is issued. The standard of care applied to telemedicine is the same standard applied in a clinic — remote delivery does not lower it. So the question worth asking an online service is not whether a clinician is involved, but who they are and what they are certified in. Curex names its clinical advisors publicly, including two fellows of the professional bodies whose practice parameters govern this treatment.

At Curex a named clinician is assigned to you and follows your course — the same person reviewing your results, setting the protocol, and adjusting it as treatment progresses. It is worth being precise about what is law and what is company policy here: US regulation requires a licensed clinician in your state and an established clinician–patient relationship, but it does not mandate that the same individual follows you throughout. That continuity is Curex’s own policy, not a legal minimum. It matters because immunotherapy runs for three to five years, and a protocol adjusted by someone who remembers your last reaction is not the same as one adjusted by whoever picks up the queue.

By blood rather than skin. Specific-IgE blood testing identifies which allergens you react to and can be collected at home, which is why remote diagnosis is possible at all. It is a genuine diagnostic test, not a questionnaire. What it does not replace is skin-prick testing, which an allergist may prefer in some situations, or the physical examination that goes with an in-person visit.

A licensed clinician does, remotely. Immunotherapy is not a fixed prescription — the protocol is reviewed and adjusted as treatment progresses and as symptoms change. If you develop symptoms that indicate the remote route is no longer appropriate, the correct response is referral to in-person care, not a dose change.

A history of anaphylaxis. Poorly controlled or severe asthma. Suspected food or drug allergy. Symptoms that are unclear or not responding as expected. Young children and pregnancy warrant in-person assessment. If you need skin-prick testing, lung-function testing, biologic therapy such as omalizumab or dupilumab, or treatment of an acute reaction, that is in-person care by definition.

Because it is sound default advice: an allergist covers every function in one place, and for an unclear or high-risk case that is exactly right. The default becomes less useful for someone with a straightforward environmental allergy who has already been tested, or who cannot realistically attend weekly appointments. In that situation the honest answer is not "skip the allergist" but "here is which functions can be handled remotely and which cannot".
