(A) Blood lead screening tests of children at risk of lead poisoning shall be conducted either by:
(1) Venous draw; or
(2) Capillary test, collected in a capillary tube or on filter paper.
(B) If the blood lead screening test is conducted by a capillary blood test collected in a capillary tube or on filter paper and the result is five micrograms per deciliter or greater, a confirmatory blood lead screening test by venous collection only shall be performed as soon as possible but no later than ninety days from the previous capillary test.
(C) Point-of-care testing using waived test methods, such as the "Lead Care® II" device, may not be used for confirmatory blood lead tests. NOTE: the level of 8µg/dL is the confirmation threshold recommended by the manufacturer of the "Lead Care® II" device to minimize possible false negatives.
(D) The director shall provide written guidance for follow up of elevated blood lead screening test results.
