Thanks for the reply.
I am looking for, if possible, incidence of population affected by lead poisoning, if any study or database has the information.
It will be helpful if we can get the total number of blood tests for lead detection in Canada per year, as it will help in finding the number of patients screened for high levels of lead.
ANSWER: 21 Jan 2008
Can you please clarify the questions before I forward them to our contacts in Canada? When you ask for information about the "incidence of human population affected by Lead poisoning in Canada", are you thinking that there might be a national study of blood lead levels in a representative number of people of all ages? I don't believe such a study has been done in Canada (but I'll ask). Or are you wanting the results of blood lead tests ordered by doctors? Do you realize that it is very rare for enough blood lead tests to be ordered by doctors to give a full picture of the incidence of lead poisoning in a population? Most people who are lead poisoned, never find out that they are.
When you ask for "Average Lead Blood Test per pediatrics in a year in Canada" do you mean "what is the average number of blood lead tests requested by each pediatrician in Canada in a year, ie the number of tests ordered by pediatricians divided by the number of practicing pediatricians?" In Australia, I believe it would only be possible to obtain the number of tests (on all ages) and divide it by the number of doctors (specialist or general) so it may be better to simply aim to get the total number of tests and hope that tests on children (up to 18 yrs) can be given as a subset. Not every pediatrician would order blood lead tests but blood lead tests can be ordered by general practitioners and by any specialist (not just pediatricians) so even if I have understood your question correctly, the answer would not be a fair assessment of the average number of blood lead tests ordered annually by Canadian pediatricians.
I look forward to hearing from you.
