About Childhood Lead Data
The Childhood Lead Surveillance module originates from the Childhood Lead Poisoning
Prevention Program (CLPPP) patient data from 1999-2005. Federal law requires that
the results from all Childhood Blood Lead tests done anywhere in South Carolina,
including public and private labs, are reported to the CLPPP. The only test results
included in this module are for children less than 6 years old based on the Center
for Disease Control and Prevention's (CDC) guidelines.
From 1999 to 2005 there was a total of 263,948 test results reported to the CLPPP.
Many of these 263,948 test cases were follow-up tests done on children over the
course of a given year. For the purposes of this SCAN module yearly files on all
tests were de-duplicated based on the child's first name, last name, and date of
birth. In any instance where one child was tested multiple times in a particular
year the case with the highest blood lead level was included and other important
variables such as race and sex were then harvested from other duplicate records
when appropriate. After this de-duplication process was completed 259,388 test cases
remained and are included in this module.
Users can select year, race, sex, age of child, region, test type, and blood lead
level as row and column variables. These same variables can be further restricted
in the drop down boxes. Frequencies and Percentages by row or column can be generated.
Users can generate on-the-fly maps and tables along with trend lines and bar charts
of the selected data.
The interpretation of tables and maps is the user's responsibility. Many supporting
pages are provided with definitions, examples, Division of Biostatistics and Health
GIS and CLPPP contact information, frequently asked questions, and links to lead
related web sites.

* >= 10 ug/dl is the level of concern specified by the CDC for Childhood Lead
Poisoning Prevention Programs.
* >= 20 ug/dl is the action level specified by the CDC for environmental site
investigation (Note: An environmental site inspection must also be done if there
is a case where 2 blood level tests result in levels between 15 and 19 ug/dl (inclusive)
on samples taken at least 3 months apart.)
* There were a total of 2,320 confirmed blood level test results from 1999 to 2005
that resulted in levels >= 10 ug/dl.In order for a test result to be considered
a confirmed elevated blood level (EBL) the test type must be venipuncture.
* There were a total of 250 confirmed blood level test results from 1999 to 2005
that resulted in levels >= 20 ug/dl. In order for a test result to be considered
a confirmed elevated blood level (EBL) the test type must be venipuncture.
