1. Don't treat in vitro genetic testing as a "luxury physical examination"
Many couples planning to get pregnant look at IVF genetic testing with the idea of choosing a physical examination package. They always feel that the basic style is "not safe," the upgraded style is "more reliable," and the luxury items are "practical." However, the core goals of the two are essentially different: routine physical examinations are to identify potential health hazards in the body, while the core of test tube genetic testing is to accurately locate the key issues that currently hinder pregnancy preparations.
If the direction of testing deviates from your actual pregnancy preparation difficulties, no matter how many items are added, it will only increase economic costs, may cause unnecessary anxiety and even delay the appropriate treatment opportunity. You know, the time cost of the IVF cycle is crucial, and blind additions will only backfire.
Different in vitro genetic testing projects have clearly defined the issues and applicable groups, and not everyone is suitable for the "full package".
Different DNA testing services have distinct targets and target populations. Not everyone is suitable for using the “comprehensive package”.
Focuson the detection target: Check whether the 23 pairs of chromosomes of the embryo have problems such as increase or decrease in number, disorder in arrangement, etc., focus only on the stability of the overall chromosome structure, and do not screen for a specific genetic disease.
Focusing on detecting abnormalities in the target organism: We check whether there are any issues with the number of chromosomes in the embryo, such as variations or disorders in chromosome arrangement. We focus solely on the overall stability of the chromosome structure, without targeting any specific genetic diseases for screening.
Suitable populations and scenarios: It is mainly suitable for elderly people who are preparing for pregnancy, multiple transplant failures, repeated biochemical pregnancies or fetal arrest, and couples with good embryo morphology evaluation but never able to implant, to help identify core pregnancy disorders.
Focuson the detection goal: Accurately determine whether the embryo carries genetic disease causing genes that have been identified by one or both parents, such as known genetic diseases such as thalassemia and spinal muscular atrophy.
Focusing on detecting target organisms: accurately determining whether an embryo carries genetic diseases caused by genes from one or both parents. Examples include thalassemia and spinal muscular atrophy, among other known genetic disorders.
Key prerequisites: "One or both parents have been medically diagnosed as carrying a specific disease-causing gene." If we are simply "worried about inheritance" and "someone in the family has suffered from diseases" without a clear diagnosis certificate and genetic locus test results, blindly doing PGT-M has basically no practical significance and is a waste of money.
Focuson detection goals: Specially screen chromosomes for abnormalities at structural levels such as translocations and inversion.
Focused detection of target abnormalities: Specifically designed to identify structural abnormalities such as translocations and inversions in chromosomes.
Fit population: Only couples who have completed chromosome karyotype analysis and have clearly detected chromosome structural abnormalities such as balanced translocations and Roche translocations. If there is no diagnosis of chromosome structure problems, it is unnecessary to force the addition of the item.
,! Too many testing items may slow down the pace of pregnancy preparation
•Available embryos may "shrink" instead
Many people mistakenly believe that the finer the testing dimension, the better the quality of the embryos selected will be. In fact, this is not the case. The stricter the testing standards and the more complex the items are, the higher the proportion of embryos judged to be "unqualified" will increase. Many embryos themselves belong to "marginal chromosomes" and have a low proportion of chromosome mosaic ", or are stuck in a certain test. Under the evaluation standards of some compliance laboratories, transplantation can be attempted. However, once multiple tests are superimposed, they may be directly determined to be" unavailable ", resulting in a reduction in the number of embryo resources that were originally available.

•Complex results exacerbate psychological internal friction
After superimposing too many testing items, couples can easily be trapped by complicated reports: "Can chimeric embryos be transplanted?" "Is this abnormal indicator serious?" "The doctor said we could try, but the report suggested that there were risks. Should we choose or not?" In fact, many couples 'journey to preparing for pregnancy is not lost at the technical level, but their mentality is dragged down by these complex test results and the original pace of pregnancy preparation is disrupted.
I have to say that some of the so-called "high-end upgrade testing projects" on the market seem to be technologically advanced, but in fact they are not of substantial help to clinical decision-whether it is judging whether to transplant or determining a transplant plan, they cannot provide decisive basis.
,“”,,--,,.In the end, the doctor may still give a suggestion that "transplant can be tried", and the extra high testing costs will become an unnecessary burden.
Judging based on age: Different age groups have differentneeds
Couples who are ≤35 years old and are undergoing IVF for the first or second time do not need to choose a full set of genetic testing immediately after they come up in most cases; for couples ≥38 years old, the detection value of PGT-A will increase significantly, so priority can be given.
Couples who are under 35 years old and are undergoing in vitro fertilization for the first or second time generally do not need to undergo a full set of genetic tests from the beginning. For couples aged 38 or older, the value of PGT-A testing becomes significantly higher, and this option should be considered first.
If high-quality embryos cannot be obtained during pregnancy preparation, there is a high probability that the problem lies in egg quality, sperm quality or ovulation promotion plan. At this time, the priority adjustment plan is more effective than superimposed testing items; if the embryo morphology is evaluated well, but there are repeated situations such as non-implantation and biochemical pregnancies, then consider investigating the problem from the genetic level .
If it is difficult to obtain high-quality embryos during the preparation for pregnancy process, the problem likely lies with the quality of the eggs, sperm, or the ovulation induction regimen. In such cases, it is more effective to adjust the treatment plan rather than simply increasing the number of tests. If the embryo morphology is good, but there are still frequent failures in conception or biochemical pregnancies, then it is appropriate to consider investigating potential genetic issues.
"Clear evidence" here refers to the basis for professional medical diagnosis, such as "confirmed diagnosis report of chromosomal karyotype abnormalities","single gene disease carrier certificate","family genetic disease locus locking results",  etc.
“”,“”“”“”.If it is just pure anxiety, or if there are cases of illness in the family but the diagnosis is not clear, don't blindly add testing items to "seek peace of mind."
In the journey of preparing for pregnancy in vitro babies, the choice of genetic testing items is one of the easiest links to "pay IQ tax".
,“”.It is not that many couples have limited financial conditions, but after blindly choosing all tests, they fall into the dilemma of "spending more money, fewer embryos, and difficult decision-making", which instead delays the progress of pregnancy preparation.
The truly mature strategy of preparing for pregnancy in vitro has never been to "exhaust all items to investigate risks", but to "accurately target the current core issues and only perform necessary tests." Only by matching testing items with one's actual needs can genetic testing become a help on the road to pregnancy preparation rather than a heavy burden.
