Re: testing genetic blood or skin?

[Guest guest]

Hi ,

When at the neurologist, first off a family history is taken and a manual exam

done (like touch your doc's finger, then touch your nose a couple of times. Also

the vibrations test, the pinprick test, the doc will also look into your eyes,

maybe a few more thing From that the neurologist will order testings either all

of these or some, starting with the EMG/NCV. From that the neurologist will

determine what test comes next.

Since the EMG/NCV can distinguish between Type 1 and 2, a skin biopsy may be

done to confirm that, or only have the skin biopsy which can also tell the

difference between Type 1 and 2. It

The DNA test is a blood test from which blood cells are used to determine what

subtype you have - example CMT 1A or CMT 2E. That is what is called 'genetic

testing'. And as you know, there are some types for which right now there aren't

genetic tests.

We are finally going to do genetic testing at the request of one of my

children. I never want to put my kids through an EMG so we are thinking about

the blood test.

We choose the blood test, there was no way the were doing EMG. :-)

Thanks

I had the Athena Labs genetic test. They drew several vials of blood. but

overall pretty painless. The report took several weeks and is several pages

long. It did identify my type...I have HNPP.

Having had an EMG done twice, I can say that it isn't THAT unpleasant. But it is

more unpleasant than giving a blood sample. :-)

The level of pain experienced by these tests may vary depending on the person. 

Pain thresholds vary in the general population.  With CMT, this variation may

be increased due to the level/type of sensory nerve involvement.  In other

words, some people experience nerve numbness, while others have increased pain

sensitivity, and others have no change.

For me, the EMG was more painful that the NCV tests - which were painful -

especially as they kept ratcheting up the intensity trying to get a response. 

Whereas the blood draw was a non-event by comparison.

I would definitely opt for a blood test, if I was given the choice.

It really depends on the type of CMT and the damage. I have had 3 EMGs and they

were more painful then having my 5 babies.

OOooohh, , I'm sorry to hear that. I had no idea it could be so bad, even

as my pain was pretty great.

But for me, the EMG was uncomfortable for a log time, but not unbearable.

I so agree with on this one. My son and I have 1A and I have never felt

the kind of pain people like have described. My son is SO sensitive and

even he does not complain about the EMG, so the pain really does vary from

person to person.
