Look for signs before symptoms.
The proposal is to identify babies who can benefit from clinical evaluation and confirmatory tests earlier.
Longevo Baby: baby genetic screening
Longevo Baby analyzes DNA for variants associated with early-onset conditions predicted by the panel. It complements neonatal screening and does not replace the heel prick test or pediatric evaluation.
Genetic information to expand the conversation about baby's first care.
Keyword: screening
Identify early who may need a more specific assessment.
Screening may signal the need to investigate a condition predicted on the panel before clear symptoms. A relevant finding needs to be related to the baby and may require confirmation.
A finding starts an investigation.
The pediatrician and specialists evaluate the result, the condition investigated, the baby's health and the need for a new sample or another method.
A negative result is not a guarantee.
The test evaluates a defined set of genes and variants and does not detect all genetic conditions, congenital or acquired.
If your baby shows signs or symptoms: seek pediatric evaluation without waiting for the results of a screening. A diagnostic investigation may be more appropriate and should not be delayed.
Complementary methods
Heel prick test and Longevo Baby observe different signs.
Using one method does not eliminate the need for the other. Each one investigates different information and has its own sample collection and monitoring period.
- 01
Foot test
Analyzes markers in a blood sample to identify suspected diseases included in the newborn screening program. Suspected cases are subject to confirmation and care.
- 02
Longevo Baby
Analyzes DNA for variants associated with conditions defined in the panel and prioritized for possible early care.
- 03
Different results are possible
A condition may be part of one test and not the other. Even when they both evaluate it, they may look for different biological signs.
- 04
Pediatric care continues
Consultations, vaccinations, growth monitoring and other recommended screenings are not a substitute for a genetic result.
Family journey
From initial conversation to follow-up.
Before sample collection, share the baby's story and ask questions about what the test analyzes, consent, results and follow-up. The flow may change depending on the child's health and the quality of the sample.
Guidance
Family and professional discuss the purpose of screening, the child's history and the limitations of the test.
Consent and sample collection
After making an informed decision, the team guides the sample collection of the oral sample and the sending and acceptance criteria.
Analysis
The laboratory evaluates the genes and variants defined for the test and reviews the findings according to technical criteria.
Conversation about the result
The report is explained in the context of the child. A screening finding may require confirmation and referral.
Follow-up
The pediatrician coordinates assessments, care and monitoring when necessary. A report without a finding does not end health monitoring.
After the result
The report guides the next step; does not make a diagnosis on its own.
The interpretation considers the classification of the finding, the baby's health status, inheritance, the quality of the analysis and what the test was unable to assess.
- 01
No reportable findings
The examination did not identify, within its analyzes and its criteria, a change to report. This does not exclude all genetic conditions or future manifestations.
- 02
Relevant screening finding
The result points to a possibility that needs to be related to the child. The team defines whether it is necessary to confirm in a new sample, by another method or with specific clinical evaluation.
- 03
Inheritance information
Some findings may raise questions about parents or other relatives. Any family test requires individual guidance and consent.
- 04
Clinical conduct
Treatment, surveillance or referral should only be defined by the assistant team after verifying that the finding is confirmed and applicable to the baby.
- 05
Result and future development
One outcome does not predict a child’s entire health trajectory. Severity, age of onset, and response to care can vary even among people with the same condition.
Limits that protect decisions
Longevo Baby is not a complete genetic check-up.
The panel was designed for a specific purpose. Questions outside this may require further examination.
Not every condition is included.
Diseases outside the selection of genes and variants in the panel are not evaluated, and the content may change depending on the current technical version.
Not every change is detectable.
Some regions and change types may require specific methods. Insufficient sample quality may also require new sample collection.
Symptoms change the question.
When there are clinical manifestations or specific family history, the pediatrician may recommend a targeted diagnostic test instead of relying on screening.

Frequently asked questions
Before sample collection and after the report.
Is genetic screening a diagnosis?
No. A screening finding indicates that the child needs more specific evaluation. Confirmation may include a new sample, another method and clinical analysis.
My baby looks healthy. Can you still do a screening?
Screening is aimed at recognizing some conditions before clear signs, but the decision must consider the family's purpose, limits and preferences. The pediatrician can help with this conversation.
What if my baby already has symptoms?
Seek pediatric evaluation without waiting for triage. Symptoms may require specific diagnostic investigation, treatment or immediate referral, depending on the chart.
Does a positive finding mean the baby is sick?
Not necessarily. The finding needs to be confirmed and related to the clinical status, inheritance and available knowledge about the condition.
Will parents also need to be tested?
It depends on the finding and the clinical question. Parental samples can help confirm inheritance or interpretation, but each family member receives guidance and consent separately.
Next step
Get to know Longevo Baby and ask your questions about screening.
The team can explain what the test analyzes, access and sample collection. The pediatrician helps relate this choice to the baby's health and monitoring.
