Maryland MDH 4620 Blood Lead Testing Certificate

Maryland requires blood lead testing at the 12 and 24 month well-child visits, and families must show the results when a child enters child care, pre-kindergarten, kindergarten or first grade. The provider lists each test date, type and result on this certificate and signs it, or documents a religious objection after a lead risk questionnaire and counseling.

Who completes it

A health care provider records and certifies the tests by signature or stamp; a school health professional or designee may transcribe and certify results from another authenticated record. The parent signs only the refusal section, if used.

Submitting and payment

How to submit it
The parent or guardian gives the completed certificate to the administrator of the child care, pre-K, kindergarten or first grade program before entry, and it is kept with the school health record.
Who pays
The certificate sets no fee and does not address payment for testing or completion.

Good to know

  • Each test row asks for the date, whether the sample was venous or capillary, the result in micrograms per deciliter and comments, with a second certification line for later tests.
  • A copy of the child's blood lead results from ImmuNet may be given to the parent instead of completing the form, under COMAR 10.11.04.05(B).
  • If the 12-month test was missed, a test after 24 months of age is sufficient; a child not tested at either visit should be tested as early as possible.
  • The guidance page notes Maryland follows the CDC reference value of 3.5 micrograms per deciliter, and an elevated capillary result needs a confirmatory venous sample.

Frequently asked questions

What if a parent refuses lead testing in Maryland?

The certificate has a section for refusal based on bona fide religious beliefs and practices. The provider asks seven lead risk questions, initials that they counseled the parent if any answer is yes, and the parent signs the objection acknowledging the potential impact of not testing.

Which lead tests go on the Maryland Blood Lead Testing Certificate?

Maryland requires testing at the 12 and 24 month well-child visits, at 12 to 14 and 24 to 26 months of age, and both results should be listed. If the 12-month test was missed, a result after 24 months of age is sufficient.

Is the Maryland lead certificate available in other languages?

The form says a copy in another language can be requested from the Maryland Department of Health Environmental Health Helpline. Providers can also hand families an ImmuNet printout of the results instead of completing the certificate.
