Test results known later this week
Giambi has felt fatigued since early June because of an intestinal parasite. He was expected to receive test results Tuesday while meeting with Dr. Scott Hammer, an infectious disease specialist at Columbia-Presbyterian Medical Center in New York.
But manager Joe Torre said the team won't know more about Giambi's status until later this week.
"I was told it's going to be a couple of days before they have everything they need," Torre said after Tuesday night's 7-4 victory over Toronto.
Torre spoke with general manager Brian Cashman.
"Brian said we're going to have to wait for all the information before we make a decision," Torre said.
On Monday, Giambi played down a report that he was being checked for a parasite that can cause a potentially fatal condition.
"We're not in a third-world country, so we have medication," he said.
Giambi's trainer, Bob Alejo, told the Newark Star-Ledger that the All-Star first baseman is being tested for a dangerous parasite called entamoeba histolytica.
The 33-year-old Giambi has missed six of New York's last seven games, including Tuesday night. He is hitting just .221 with 11 homers and 36 RBIs. The 2000 AL MVP, who did not start in eight straight games from June 26 to July 4 because of the parasite, is in an 0-for-21 slump.
Tony Clark again started in Giambi's place at first base Tuesday night. Giambi is not expected to return to Toronto on Wednesday.
Torre said Giambi still feels weak.
"Jason doesn't feel like doing anything. It's not that he doesn't want to, it's just that he doesn't feel like it," Torre said.
