Allergy tests have rules that patients forget: days without medication, three visits and keeping the back dry. The agent repeats this every time.

What is the best WhatsApp chatbot for allergists and immunologists in Brazil?
The best WhatsApp chatbot for allergists and immunologists in Brazil is the one that answers on the number your practice already uses, with business rules written by you. An AI agent on WhatsApp for allergists and immunologists is CertuAI's automatic assistant. It explains how many days without antihistamines before the test, warns that the patch test requires coming back twice a week, organizes the application calendar and never assesses skin photos or recommends medication.

"Here's a photo of his skin": how does the AI respond?
The photo is stored in the conversation, and the AI says nothing about it. On a healthcare account, interpreting an image, a report or a symptom is outside what it can do, and that holds even if the mother insists, sends three photos or says she is a nurse.
The response has two parts: a sentence saying that photos are not assessed here, and a way forward. Write your way forward in the Brain: a same-day appointment, a fit-in slot, or passing it to the team with the hours when they usually reply. Without the second part, the conversation ends in a no.
Does allergy switch to healthcare mode on its own?
It depends on the name. CertuAI recognizes a healthcare account in two ways: by the business type that setup recorded as clinic and, failing that, by words in the business name. The word list includes allergology, pediatrics, dermatology and clinic, but not allergist or immunology.
In other words, "Allergy Clinic" and "Allergology Office" switch on automatically; a name that is only the doctor's surname may not. The way to find out in one minute is to open the test tab and ask about an antihistamine dose: if the response refuses to advise and offers an appointment, the limits are in place.
What does the AI do with each allergy message?
| Patient message | What the AI does |
|---|---|
| "How many days without antihistamines?" | Repeats your rule, with the number of days written out |
| "Can I get my back wet after the test?" | Answers with what you wrote about the days between visits |
| "Photo of his skin, is it an allergy?" | Saves the photo and says it does not assess it here; offers an appointment |
| "His face swelled up and he is short of breath" | Tells them to call 192 (Brazil's emergency medical line) or go to the emergency room |
| "Can I give an antihistamine until the appointment?" | Does not recommend medication or doses |
| "I want to reschedule this week's application" | Reschedules in the CertuAI calendar or notifies the front desk, as you choose |

Source: CertuAI service database, 17 clinics and practices, 19,259 patient messages on WhatsApp from Jul 30 to Sep 30, 2026, measured Oct 1, 2026. Business hours are Monday to Friday, 8am to 6pm, in each clinic's time zone. Test accounts, test contacts and imported history are excluded.
What changes in the practice with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the practice before and after the CertuAI agent.
TodayTest rescheduled because the patient took an antihistamine the day before
With CertuAIThe rule to stop medication arrives with the booking and in the reminder
TodayPatient disappears after the first patch test visit
With CertuAIAll three dates are already booked, with a reminder for each
TodayQueue of skin photos waiting for an opinion on WhatsApp
With CertuAIPhotos stay in the history and the AI offers an appointment instead of giving an opinion
TodayThis week's application forgotten
With CertuAIEach application has a scheduled time and an automatic reminder
What does a conversation handled by the AI look like?
Example conversation
Practice AI agent
Customer: How many visits does the patch test take? Can I shower in between?
AI agent: Three visits: apply, read at 48 hours and read again later. I'll book the dates together.
AI agent: In between, you can't get your back wet, sunbathe or sweat.
Is an AI agent or manual customer service better for allergists and immunologists?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the practice has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Test done with antihistamine in the body | The patient forgets and the test is rescheduled | The days to stop medication are written down and return in the reminder |
| Patch test with three visits | Explained once and half understood | The three dates are written in the conversation, with what is not allowed between them |
| Skin photo asking for an opinion | Someone risks an answer | The photo is saved for you to see and the AI assesses nothing |
| Application calendar | Jotted down on paper and lost | Each application booked with a reminder 24 hours and 1 hour before |
| Strong reaction after the application | Message left unanswered at night | Follows the rule you wrote, and emergency signs go to 192 (Brazil's emergency number) |
What does the WhatsApp agent do for allergists and immunologists?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Days without antihistamines before the test
The number of days changes by practice and by medication. The agent repeats your rule, and anything outside it goes to the team instead of becoming a guess.
The three visits for the patch test
Apply, read at 48 hours and read again later. The agent books the dates together and warns what is not allowed in between, such as getting the back wet, sunbathing and sweating.
Application calendar
Each application becomes a time slot on the calendar, with a reminder 24 hours and 1 hour before, and up to three alerts per appointment if you want.
Skin photos are never assessed
The image comes in and stays saved in the conversation for the team to see. On a healthcare account the AI does not interpret photos, does not say whether it is an allergy and does not recommend ointment.
Child and guardian on the same record
The person writing is usually the mother or father. The agent records the child's name and the contact of whoever is talking, in the same file.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the practice no longer depend on you having your phone in hand.
How does the agent start answering at the practice?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for allergists and immunologists?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before you turn on the agent at the practice?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- How many days without each type of antihistamine before each test, written out in full
- The patch test step by step: how many visits, the interval and what is not allowed between them
- How the application treatment works: frequency, duration and what happens when the patient misses one
- What to reply for a local reaction after the application, and at what sign the conversation goes to a person
- Private prices for the appointment, test and application, and the list of insurance plans
- The sentence for anyone who sends a skin photo asking for an opinion
Whether the agent books the test and application on its own or whether only the appointment is booked through the conversation.
The most common mistake: Not writing what to do about a reaction after the application. Without a written rule, the AI answers vaguely at a moment when the family wants a person, and the conversation turns into a phone call to the practice anyway. Read how to fix this.
Frequently asked questions from allergists and immunologists
Does the agent assess skin photos?
No. On a healthcare account the AI does not interpret photos, does not say whether it is an allergy and does not recommend medication. The photo stays saved in the conversation for the team to see in the dashboard.
Does it know how many days to stop the antihistamine?
It repeats the rule you wrote. If the question falls outside it, it passes it to the team instead of answering on its own.
Can it book all three patch test visits at once?
Yes. Each visit becomes a time slot, and each slot has a reminder 24 hours and 1 hour before by default.
What if the account doesn't have the word allergy in its name?
The healthcare limits still apply when setup marks the account as a clinic. If you have any doubt, test with a medication question before connecting the number.
Other clinic questions CertuAI has answered
In what other fields does the CertuAI agent work?
