Genetic tests provide essential information about hereditary predispositions. We perform advanced DNA analyses interpreted by experienced geneticists.
Genetic analyzes are medical tests that identify changes at the level of genes, chromosomes, genome or proteins. Depending on the purpose, they can be used to confirm a clinical suspicion, to assess hereditary risk, to screen before or in pregnancy, or to clarify some results obtained through other investigations. The NHS and MedlinePlus stress that genetic testing must be understood in the context of the medical question to be answered, because not all genetic tests have the same utility or the same type of result.
Genetic analyzes may be recommended when there is a suggestive family history, suspicion of genetic disease, abnormal results on other investigations, difficulty conceiving in certain contexts, repeated miscarriages, prenatal suspicions, or the desire to assess hereditary risk before pregnancy. Some tests are also used for carrier screening, to estimate the risk of having a child with certain genetic conditions.

Genetic analyzes are not a single type of test, but a very broad group of investigations. MedlinePlus describes several categories, including diagnostic, predictive and presymptomatic tests, carrier tests, prenatal tests, neonatal tests, pharmacogenetics, and extended genomic testing such as whole exome or whole genome sequencing. The choice of test always depends on the medical reason for which it is recommended.
For a correct assessment, it is important to follow some essential steps:
Let's clarify the medical question to which the test must answer.
Let's choose the right test together with the doctor.
Let's understand the difference between screening and diagnosis.
Let's interpret the result in clinical and family context.
Let's discuss the implications of the result for the patient, and sometimes for the family.
1.An essential aspect is the difference between screening and diagnostic tests. Genetic screening estimates whether the risk for a particular condition is higher or lower, while diagnostic tests are used to identify or confirm a genetic condition. That means that a positive screening result is not automatically equivalent to a definite diagnosis.
2.Genetic analysis can have important benefits. The results can reduce uncertainty, guide prevention, monitoring, or treatment, and support decisions about pregnancy, family, or future medical care. At the same time, some health systems, such as NHS England, stress that testing is most useful when there is a reasonable probability that the result will change medical conduct for the patient or family.
3.Genetic results must be interpreted carefully. MedlinePlus explains that a result can be positive, negative or inconclusive, and its meaning depends on the context. Sometimes a test may not fully explain symptoms or be unable to predict the severity, course, or timing of a disease.
4.Genetic testing also has limits and can have emotional, social or family effects. These include results-related anxiety, questions about other family members, and the possibility that a result generates more questions than answers. For this reason, talking to your doctor or a genetics specialist is especially important.
5.In the reproductive and prenatal context, ACOG recommends that carrier screening and genetic testing be clearly explained, including in terms of what the test can and cannot show. In pregnancy, there are both screening tests and prenatal diagnostic tests, and the choice must be made informed and phased.
We ask ourselves the question of genetic analyzes when there is a suspicion of a hereditary disease, when there are several similar cases in the family, when it is desired to assess the risk of transmission to children, or when a clinical or imaging result requires further clarification. In many situations, the most important stage is not just conducting the test, but its correct choice and professional interpretation of the result.
At CMIB, we approach genetic analyses through careful, personalized, and focused assessment to choose the right test, interpret the result correctly, and understand the medical and family implications. Schedule a consultation and find out which genetic tests are recommended in your case.
Genetic analyzes are medical tests that look for changes at the level of genes, chromosomes, genome, or proteins associated with certain conditions.
They can be used to confirm or exclude a diagnosis, assess disease risk, carry screening, prenatal testing, or guide medical decisions.
People with suggestive family history, suspicion of genetic disease, couples who want evaluation before pregnancy, pregnant in certain situations, and patients in whom other investigations raise suspicions of genetic cause.
In general, it means that a genetic alteration relevant to the investigated medical question has been identified, but the exact significance must be explained by the doctor in a clinical context.
