DES MOINES, Aug. 31 — The Iowa Supreme Court agreed Friday to review a judge's ruling ordering the state's Planned Parenthood chapter to turn over pregnancy test results to investigators.

Buena Vista County investigators are seeking the records in an effort to identify a dead baby boy found in May at a recycling center in Storm Lake, in northwestern Iowa.

Planned Parenthood says the test results are confidential medical records.

Planned Parenthood appealed an order to turn over the names and addresses of all women with a positive pregnancy test between Aug. 15, 2001, and May 30, 2002.

Judge Frank B. Nelson of State District Court had ordered the information to be turned over by Aug. 17, but the Supreme Court granted Planned Parenthood a delay. A hearing is expected the week of Dec. 9.

Philip E. Havens, the county attorney for Buena Vista County, contends that the results are not medical records because employees who perform pregnancy tests do not have to be doctors or nurses.
