The above explanation should help a bit in explaining the procedure[s]. I've found no problems in having a second opinion where the specialist wanted to do the tests by his/her standards and the quality of testing can vary due to the equipment used or how the test results are interpreted.

I've had the 'few' point tests, and the 'many' point tests..I'd want to get a copy of the test results then do web searches on what it all means - the meaning of it all is the hardest to grasp, but its worth having in hand.

Don't worry yet, wait for the results - j
