Last week I received partial LP results and finally called today for the IgG index and o-bands results.
I am confused!!! This was done at Yale, and yes, serum was drawn just prior to the LP.
The results I received today indicate that no oligoclonal bands were observed in ether the CSF or the serum.
The serum IgG value was 509 (low) with a reference range of 700 - 1600 mg/dl.
BUT...the IgG CSF index result states "the CSF index can not be calculated."
If they were able to complete the test for o-bands, I don't understand why they would not be able to calculate the CSF IgG index, unless perhaps there was a lab error? Anyone have any guesses? The formula itself does not lend itself to errors.
They did run a test for myelin basic protein results 1.45 (high) with a reference range of 0.0 - 1.1.
CSF lymphocytes appear high, if I am reading things correctly. Lymphocytes show a value of 90, monocytes show 10; from what I can tell, the lymphocytes should range up to 70%, so these values indicate an inflammation or a chronic process taking place in the CNS.
I don't know what this all means at this point. I was hoping that with the elevated MBP, I would show o-bands or an elevated IgG index.
While I am impatient for a diagnosis, I also understand the importance of making the right diagnosis.
Can I say this aspirates?
