LeadCare II

Hello - I received a letter from our state DOH today regarding our LeadCare - They sent a Lead Testing Quick Guide for the Magellan LeadCare II and in their disposal section it says:
1. Use an estimated four drops (40uL each) of 7.5% NaHCO3 neutralizing solution, to neutralize remaining contents in reagent vial to a pH between 2.0-12.5. (I just tested the pH of the solution - it's 1.0!)
2. Dispose the solution along with other materials in bio-hazard container.
I thought maybe the LeadCare instructions had changed and I didn't know (we haven't been neutralizing anything) so I checked an open box and the insert doesn't say anything about disposal other than into biohazard.
My question: do you neutralize every LeadCare vial you use? Is this standard procedure that I just never knew about? Where do you get NaHCO3 drops?
I'm going to email the DOH as well but wanted to know if anyone was already doing this~

I have never heard of neutralizing the solution once the test is finished. We do not do this at the office that performs this test. I will be interested in what Magellan has to say.
