Yes, but some of the information is still valid, which is why it's open. Sometimes questions that don't come up as often do tend to get much older than on the busier groups. There is a post regarding this pinned to the first page of the group.
Sharon - they are the same test, unless they counted them separately (some do) for counting the chromosomes (karyotype) as one test, then looking at each one for major abnormalities as the mircroarray. Most clinics list it as one test, but not all.

this is for anita posted on 3/11/14 if you haven't found a place Quest Diagnostic Clinics do the test and if you have Medicaid they take that too I am taking my granddaughter tomorrow to have the test done My question is Is it just a regular blood test and then send to lab to have results done thanks good luck and god bless

it can take a while we live in central ny and the sample had to be sent to washington state for the test we had to wait almost 2 months so it can take a while if there is a family history its a good idea to get each child checked with us since their dad has the abnormality and i don't each of our children have a 50/50 chance of having this no matter how many kids we have with it the chances are the same so we now have 4 kids all have the same abnormality and all have different symptoms outr oldes has skin issues weak immune system hearing loss constipation issues facial tics low muscle tone hips rotate in tiny stature and many developmental delays for short our daughter has chronic loose stools other gi issues very tall and stocky more like a 10 yr old than a 8 yr old immune issues sensory issues exct the 4 yr old has passive seizures add autistic chronic loose stool developmental delays sensory issues exct the 2 yr old boy is the most normal has the loose stool issue and has a small delay in fine motor but thats about it so even though they may each test positive it doisn't mean that they automatically have this that or the other thing that will or won't happen it just depends on each individual but it does mean to be watching for those things as they are more prone to those issues like if the problem came back with a marker known for heart issues dosn't mean they will have heart trouble just means its a good idea to watch for it cause they are more likely to have those issues each gene plays a different rols and how they are combined duplicated or deledted has a unique affect on each person i am soo glad we had it done it helps to look things up when you get the results back and do some research i know it helped me understand more of what is going on but in our case there is no research my kids are it for studies so we are just playing this whole thing by ear we just know there are 2 simmilar syndromes and i have researched them to get a better idea what COULD happen with ours hope all goes well and that you got the results by now good luck :)

we were told it is the next step after karotype testing we had the karo type test done with our oldest it showed an abnormality on the 18th chromosome butr they din't know the specifics of that abnormality so they did the microray test and it showed much more detail it showed he had a partial trisomey 18 with an inverted duplication and deletion he has 28 duplicated genes and 15 deleted and they were able to tell me exactly what genes were affected only one of teh deleted genes have ever been studied so we only have a very small amount of info about then they tested my husband and myself he also has the same abnormality and then htey tested our other 3 kids they too have it so far there are only 5 people known to exist in the whole world with this disorder so it can tell some things it all depends on the dr if they orderr them seperately or at the same time ours dosn't do this test unless something shows up first

my son has got to have the microarray test and the chromosome test does anybody know the difference,i have read both definitions and they are basically saying the same to see if his problems are genetic but why do both tests then.any further information gratefully accepted.

We have just had the same testing done. Got the results, positive. duplacation of chromosome x. His peds. basicly said that is where the cognitve Impairment (mentally disabled) comes in tow. We are going to see a chromosome specialist so they can explain more in detail. They wanted me to be tested as well. But I will decline. for we can't have more kids and I will not put myself through the blame game again. I went through that already. Although my girls want to be tested in future to see if they are a carrier. They say that will not detrime if they have children just so they are prepared. Your best bet would be to talk to your dr. I looked a lot of that up on line. Just cause we don't see the specialest til Jan. We already knew that he was CI but this tells us why instead of always wandering. Good luck to you!!!!!

Microarray testing is the most genetically sensitive test they have currently in the field. it's relatively new. This test will show any genetic anomalies your child could possibly have. Therefore, if your genetic screening for this microarray comes back negative..you can rest assured that your child does not have any of the genetic mutations or syndromes tested. If something does come back positive this simply means that you have a genetic marker for this and they will probably do further testing to determine if your child has this genetic mutation.
My son has multiple anomalies and he had a stroke in uero so they ran a microarray to determine if he had a syndrome, duplication, mosaicism..they will run a battery of gene testing . Luckily, his came back negative. So we have not pursued any further testing.

I am going through that right now, so I can join you in the confusion. My son had that test ran and the doctor said that he had a duplication on his microarray but they weren't sure what it meant, and that his dad and I had to get tested to see if we had it too. And that was all they said, we go next week to find out all the results and to find out what it means. I will get back with you and let you know what I find out, but would also love to hear from some moms who have been there.
