Any Opinion on CGH vs Microarray?

Last week, I was catching up with some of my fellow IF bloggers posts that I have missed in the last 2 months. One thing that caught my eyes was Mamasoon’s CGH results - or should that be “no results”.

So I sent an email to my IVF Nurse and asked her about a “recent botch up of CGH test” and whether microarray is applicable for my egg (not embryo) case, does CGH and microarray differ in cost, and whether microarray is “safer” than CGH. She did not send me an email response but when we talked on the phone she told me she would get me the answers to my questions.

Last Monday, I got a surprise call from Dr Sch instead He sounded a bit miffed (I think) but he does understand that we in the IF blogosphere have a unique culture such that word gets out fast here. He said that it was not a botch job (like someone dropped an embryo or someone skipped work, etc.) but was instead attributed to the variations in the enzyme/reagent used. (I used to work with chemicals too so I understand what he means. It is still is not acceptable not to have quality control on the incoming enzyme/reagents though.)

Dr Sch stated that the choice of CGH vs microarray was typically made by them based on which lab has a shorter turnaround for the load that they have at the time that the samples are available. He also stated that they do not favor one test over the other and in fact, consider them equivalent. (I wonder if they did a study on this?) I do remember him saying these on our first phone consult though so he is still consistent. He did say that if I wanted to choose one over the other that I was welcome to do so. Based on what he said though, I would like to go for whichever would have faster results when my samples are available. Any of you have an opinion?

I told him that I needed to ask those questions I asked because of the “data” I got from the web. And I backtracked, I called it “information” instead of data. And that’s when he gently laughed and said “that anything you read in the web, you should not treat it as “data”". I agree. But I still would ask. No harm in asking, right? I’m paying good money for all these!
