Good move to get the lead levels checked every so often.
Been doing mine at every annual physical checkup, because of reloading, shooting indoors, handling quite a bit of lead. Lead Level has consistently been LL<3.3 micrograms/deciliter.
(FWIW, onset of lead poisoning is generally considered to take place at 40 micrograms/deciliter.)
The thing we all have to watch out for is when the iron in our blood turns to lead in our butts. Gettin' there.
