WASHINGTON (AP) _ A major chain of clinical laboratories was named Thursday on a government list of labs cited for poor performance, fraud or abuse.

The list, required by a 1988 law, named three laboratories, including National Health Laboratories which the government said operates in most states. The states were not listed.

''We want both physicians and patients to have access to this information so they can select the best labs available for diagnostic testing to support their medical decisions,'' said Bruce C. Vladeck, administrator of the federal Health Care Financing Administration.

The Clinical Laboratory Improvement Amendments of 1988 required that the list be released to the public and physicians.

On the list as of Dec. 31, 1992:

-National Health Laboratories. The company pleaded guilty to submitting false claims to government health insurance programs, including Medicaid and Medicare, and agreed to pay more than $110 million in civil and criminal penalties. The settlement permits the company to participate in Medicare and Medicaid.

-Clinical Regional Laboratory in Hazelcrest, Ill., was convicted of false billing under Medicaid and is excluded from participating in Medicare and Medicaid for 10 years.

-Daniel Wallach, M.D., who operated a medical practice in Owings Mills, Md., was convicted of one count of felony Medicaid fraud. The practice has been sold and is no longer operated by Wallach. He surrendered his license to practice medicine in Maryland and has agreed not to participate in Medicaid for five years.
