Confidentiality of Lead Test Results
Operative Text
(A) The Director shall maintain the confidentiality of lead test results and shall not disclose lead test
results or other medical information which, because of name, identifying number, mark or description,
can be readily associated with a particular individual or the individual’s parents/guardians, or any
information that could be used in combination with other information to identify an individual, except
to:
(1) the individual’s parents or guardians if a minor or to the individual if 18 years of age or older;
(2) the individual’s health care provider;
(3) anyone authorized in writing by that individual or the individual’s legal representative;
(4) authorized Department personnel or local health officials;
(5) authorized staff at another state health department if the individual is a resident of that state;
(6) anyone authorized to receive such information pursuant to a court order; or
(7) authorized staff from a Federal agency;
(8) any researcher approved by the Department to conduct a specific study pursuant to M.G.L.
c. 111, § 24A, and when approved by an Institutional Review Board.
(B) All individually identifiable lead testing results shall be considered confidential and shall not be
available as a public record under M.G.L. c. 66.Under 105 Mass. Code Regs. 460.070, lead test results and related medical information that can be linked to a specific individual are treated as confidential records. The Director of the relevant state program is required to keep this information private and may only share it with a defined, limited set of recipients — such as the individual's parents or guardians, their healthcare provider, authorized government personnel, or parties with a court order or written authorization. Individually identifiable lead testing results are explicitly excluded from public records access under Massachusetts public records law.

Section 460.070 of 105 Mass. Code Regs. 460.000 governs the confidentiality of lead test results, and property owners and managers should understand that this information is held by the state — not by landlords — under strict privacy protections. Compliant operators generally avoid requesting, collecting, or attempting to access individually identifiable lead test results through public records channels, as such results are expressly excluded from public disclosure. Landlords who receive any lead testing information through authorized channels are generally expected to handle it with care and in accordance with applicable privacy requirements.

Under 105 Mass. Code Regs. 460.070, a child's lead test results are confidential and may be shared with the child's parents or guardians and healthcare provider, but are not available to the general public as a public record. Tenants and families have a right to receive their own or their minor child's lead test results directly, and written authorization is required before that information can be shared with most other parties. Individuals who believe their confidential lead testing information has been improperly disclosed may wish to contact the Massachusetts Department of Public Health or consult a tenant-rights organization for guidance on available options.
