(2) If a minor patient resides in 1 of the jurisdictions identified in R 330.303 as a geographic area  
where children are at high risk of lead poisoning, a physician treating the minor patient shall test,  
or order a test, for lead in blood of the minor between 48 months and 60 months of age.  
(3) If a physician determines that a minor patient is at high risk for lead poisoning, the physician  
shall test, or order a test, for lead in blood of the minor as provided in subrules (4) and (5) of this  
rule.  
(4) If either of the following factors that identify a minor at high risk for lead poisoning are

(a) The minor resides in a home where other minors have been tested and found to have lead  
poisoning.

(6) The department shall make available educational materials for physicians regarding health

blood lead testing may be indicated.  
(7) If capillary blood lead test results are equal to or greater than the blood lead reference value,  
the physician shall test, or order a test, for lead in blood with venous blood. The venous blood  
lead test must be analyzed in a laboratory using a high complexity method, such as inductively  
coupled plasma mass spectrometry or graphite furnace atomic absorption spectroscopy.
