A laboratory is a business where the client schedules, the client shows up, and yet the service may not happen — because they ate, took medication, forgot the medical order, or came at the wrong time for that test. Each of these situations is a lost collection, a broken schedule, and a frustrated patient who will complain about the laboratory for an error that originated from unclear instructions. It is the sector where communication before service matters more than anywhere else.

Absences that are not due to lack of interest
When a patient doesn’t show up or arrives unprepared for collection, the easy assumption is that they were disorganized. The correct interpretation, most of the time, is that no one explained it clearly enough to follow.
The causes repeat with a regularity that reveals the problem:
- Fasting not observed, or observed for a different duration than required
- Medication that should or should not have been suspended, without clear medical guidance
- Test requiring collection at a specific time but scheduled for another
- Material that should have been collected at home but wasn’t, or was collected incorrectly
- Medical order forgotten, expired, or illegible
- Insurance card or document not brought
None of these are the patient’s sole fault. All are solved with the same thing: the right instructions for that test reaching their device beforehand.
Printed instructions are given on the day of scheduling and read — if read — at that moment. Preparation happens the night before, when the paper is elsewhere. A message arriving the night before, short and only with what matters for that test, is read at the moment the decision is being made — and that’s why it works and paper doesn’t.
Scheduling a test is different from scheduling a consultation
A consultation needs a time slot. A test needs a time slot, preparation, material, medical order, and sometimes authorization — and any of these can prevent service on the day.
What needs to be resolved at scheduling, not at reception:
Which tests the order covers. Each has its own preparation, and the combination defines the actual fasting, usually the longest among them.
If there is a time requirement. Some tests have a specific collection window, and scheduling outside it means repeating.
If the insurance requires prior authorization, and if it has already been obtained — finding this out at reception is the most common reason patients go home.
If the patient needs to bring material collected at home, with the container delivered beforehand and instructions on how and when to collect.
If there are relevant restrictions, such as pregnancy, small children, or mobility difficulties, which change the room, professional, or even the service location.
Five questions at scheduling prevent most absences and rework — and all fit into a WhatsApp conversation with a photo of the medical order.

What can and cannot be transmitted
This is where laboratories need to be more careful than any other segment: practically everything that circulates is sensitive personal health data, with specific protection under LGPD, in addition to the professional confidentiality governing the area.
A practical separation that works day to day:
- Can circulate freely: appointment confirmation, preparation instructions, address, what to bring, notification that the result is ready.
- Requires extra care: test name associated with the patient, since the test name itself reveals health information.
- Should not circulate freely: results, reports, images, and any analysis values. The path is the portal with authenticated access, and the message only notifies availability.
Three precautions apply to any laboratory: explicitly and recorded consent for contact; identity confirmation before handling any sensitive matter, because phone numbers change owners; and restricting who on the team has access to patient history. It’s worth reviewing this setup with whoever is responsible for LGPD compliance in the company — the cost of getting it right is small, and the cost of error with health data is not.
Delivering the result, where the patient forms their judgment
The patient forgets the needle but remembers the wait. The perception of quality in a laboratory is formed almost entirely between collection and having the result in hand.
What solves it:
- State the deadline at collection, per test, not a generic deadline. Different tests are ready on different days, and patients waiting for the whole set get unnecessarily irritated.
- Notify when ready, without the patient needing to ask. This message generates the most positive feedback in the sector.
- Also notify when delayed, with the reason. Communicated delays rarely cause complaints; discovered delays always do.
- Explain how to access, with the portal link and step-by-step instructions, because a significant portion of the audience gets stuck exactly there.
- Never interpret results via message. Interpretation is for the doctor, and this boundary must be communicated clearly and kindly.
Insurance and private are two separate operations
Many laboratories treat both as the same queue and lose money on both.
With insurance, the price isn’t yours, the margin is tight, and volume, denials, and payment timing decide the outcome. Commercial work is with referrers — doctors, clinics, and operators — and operational work is avoiding denials due to authorization, guide, or incorrect documentation.
With private patients, you set the price and the patient compares. Here it’s worth having fixed-price check-up packages, conditions for combined tests, and a sales path that doesn’t involve any insurance.
The conversation most laboratories don’t have: offer private service for tests not covered by insurance. When a test on the order isn’t covered, the standard response is to say it’s not possible. The response that generates revenue is to inform the private price for that item and resolve it in the same visit.
One year in numbers
Neighborhood laboratory, two collection rooms, serving insurance and private patients.
- Collections performed in the year: 9,480
- Scheduled appointments that did not convert: 214 — absences, unprepared arrivals, and patients sent home due to lack of authorization or documents
- Average ticket per service, mixing insurance and private: R$ 96
- Direct loss: R$ 20,544, not counting idle room time and rescheduling rework
The laboratory began sending specific preparation instructions the night before, confirming authorization and documents the day before, and sending the list of what to bring along with the address.
The following year, with similar volume: 68 lost appointments, compared to 214. Recovery of R$ 14,016 in revenue that was already scheduled — and, more importantly, 146 time slots that were reused.
A prepared patient is served faster, increasing the capacity of the same two rooms. Reception stops spending the day explaining preparation and resolving authorization and starts serving again. In a laboratory, reception time is capacity — and it was being consumed by conversations that a message the night before solves.
Home collection: the service that changes the ticket
Home collection has ceased to be an exception and has become a relevant line, especially for the elderly, people with mobility difficulties, small children, and those who simply don’t want to go.
Its organizational demands differ from in-unit collection: routing by region so the professional doesn’t cross the city, informed and respected time window, confirmation the night before with preparation, and logistical care with transporting the material under required conditions.
Commercially, it is the service with the best ticket and highest loyalty, because those who start collecting at home rarely return to travel. It’s worth having pricing by region, minimum per visit, and conditions for more than one person at the same address, which is the most profitable and common scenario in families.
Occupational testing and the bill that doesn’t disappear
While the laboratory competes patient by patient, there is a client who brings dozens per month under contract: the company that needs occupational tests for hiring, periodic exams, role changes, and dismissal.
What this client needs and almost no laboratory delivers in an organized way: scheduling without HR having to call each employee, certificates returned on time and in the correct format, consolidated monthly billing instead of guide by guide, and a direct contact to resolve issues.
It is a predictable portfolio, with on-time payment and almost automatic renewal — and the work to win it is follow-up, not counter service, which is exactly what is lost when everything lives in the memory of whoever serves.
The follow-up each test already announces
Many laboratory tests have known periodicity: monitoring chronic conditions, control after treatment start, annual routine tests, follow-up requested by the doctor in the report.
Recording this date at collection and notifying when it arrives is the cheapest recipe a laboratory can have, because it is a patient who already trusts, already knows the path, and doesn’t need convincing. The minimum cadence: notification when follow-up approaches, annual check-up reminder for those who had one the previous year, and contact with those who have been absent for more than eighteen months.
Five mistakes that cost collections
- Sending generic preparation instructions. The patient needs the instructions for their specific test, not a list of all.
- Discovering authorization at reception. It’s the most common reason patients go home.
- Sending results via message. It is sensitive health data and the path is the authenticated portal.
- Giving a generic deadline. Tests are ready on different days, and poorly informed waiting turns into complaints.
- Not recording the date of the next test. It is the laboratory’s cheapest recipe, and it disappears due to lack of notation.
Numbers to track
- Lost appointments, classified by reason: absence, preparation, authorization, document.
- Percentage of appointments with instructions sent the night before.
- Average time between collection and result availability, by test type.
- Insurance denials, by cause, where margin escapes.
- Average ticket separating insurance, private, home collection, and occupational.
- Patients who returned within the expected timeframe of the test itself.
A laboratory is a precision business that loses revenue due to communication. The right instructions the night before, authorization checked in advance, notification when the result is ready, and the next test date recorded turn absences into services and a one-time patient into a years-long relationship.
Frequently Asked Questions
Why do so many patients miss appointments or arrive unprepared for collection?
Almost always because the instructions didn’t arrive in a way that could be followed. The causes repeat: fasting not observed or observed for a different duration than required, medication that should or should not have been suspended, test requiring collection at a specific time but scheduled for another, material that should have been collected at home but wasn’t, medical order forgotten or expired, and insurance card or document not brought. None of these are the patient’s sole fault, and all are solved with the same thing: the instructions for that test reaching their device beforehand. The paper given at the counter doesn’t solve it because it’s read on the day of scheduling, while preparation happens the night before — the message arriving then is read when the decision is being made.
What can be sent via WhatsApp in a laboratory?
Practically everything that circulates in a laboratory is sensitive personal health data, with specific protection under LGPD and subject to professional confidentiality, so a practical separation is worth it. Appointment confirmations, preparation instructions, address, what to bring, and notification that the result is ready circulate freely. The test name associated with the patient requires extra care, since the test name itself reveals health information. Results, reports, images, and any analysis values should not circulate freely: the path is the portal with authenticated access, with the message only notifying availability. Three precautions always apply: explicit and recorded consent for contact, identity confirmation before handling sensitive matters since phone numbers change owners, and restricting who on the team accesses the history.
What needs to be resolved at scheduling?
Five things, and none should appear for the first time at reception. Which tests the order covers, since each has its own preparation and the combination defines the actual fasting, usually the longest among them. If there is a time requirement, since some tests have a specific collection window and scheduling outside it means repeating. If the insurance requires prior authorization and if it has already been obtained, the most common reason patients go home. If the patient needs to bring material collected at home, with the container delivered beforehand and instructions on how and when to collect. And if there are relevant restrictions, such as pregnancy, small children, or mobility difficulties, which can change the room, professional, or even the service location. All fit into a WhatsApp conversation with a photo of the medical order.
How valuable is organizing communication before collection?
In a neighborhood laboratory with two rooms and 9,480 collections per year, 214 appointments did not convert — absences, unprepared arrivals, and patients sent home due to lack of authorization or documents. At an average ticket of R$ 96, this is R$ 20,544 in direct loss, not counting idle room time and rescheduling rework. After starting to send specific preparation instructions the night before, confirming authorization and documents the day before, and sending the list of what to bring along with the address, the following year closed with 68 lost appointments instead of 214 — R$ 14,016 recovered and 146 time slots reused. The biggest gain doesn’t even show in this account: prepared patients are served faster, and reception stops spending the day explaining preparation to start serving again.
Which revenue lines does a laboratory usually overlook?
Three. Home collection, which has the best ticket and highest loyalty, because those who start collecting at home rarely return to travel — it requires routing by region, respected time window, confirmation the night before, and logistical care with transporting the material, and it’s worth having pricing by region, minimum per visit, and conditions for more than one person at the same address. Occupational testing, which brings dozens of people per month under contract with predictable payment, and whose differential is scheduling without HR having to call each employee, returning certificates on time, and consolidated monthly billing. And private service offered to those not covered by insurance: when a test on the order isn’t covered, the standard response is to say it’s not possible, while the response that generates revenue is to inform the private price and resolve it in the same visit.
