Re: Question regarding Selective Antibody Deficiency testing

[Guest guest]

Most specialists will want to see a panel done before the appointment. There is

a 12 titer lab and a 23 titer lab. Response can be determined by two ways.

Either a response between pre and post vaccination labs of a set level. Usually

2 is the number. Or some doctors want to see a fold response. Which means even

if the level is under 2 if it tripled then that is considered response. It is

best to send the pre and post blood draws together. Labeled as such. That way

the same tech and processing protocol are used on both. Technique is

everything.

Subject: Question regarding Selective Antibody Deficiency testing

Hi,

Sorry if this is a very basic question for the experienced members on the board.

I am trying to determine if my son might have selective antibody deficiency due

to an impaired response to polysaccharide vaccines.

We recently checked his titers to HiB, MMR, Varicella, Polio, DTaP vaccines. His

titers to Pertussis and Polio are negligible. Could this give him a diagnosis of

selective antibody deficiency?

If not, what criteria qualifies one for selective antibody deficiency? Do I also

need to ask my pediatrician to order a test for S. Pneumoniae titers (from his

pneumococcal vaccine) before the diagnosis can be made?

I would really appreciate any guidance.

Thanks
