Ever wonder what happens to that tube of blood after the doctor draws it from your body?
Students from Polytechnic High School in Sun Valley found the answer to that question while touring Kaiser Permanente Regional Laboratory in North Hollywood on Tuesday.
With the blood, the students learned the cells are separated from the serum in centrifuges before testing.
Fifteen teenagers from the math and science magnet school visited the facility, one of the nation's largest medical laboratories that performs 10 million procedures a year.
"This [tour] helps to wake up the students and get them motivated," said biology teacher Hector Colon. "That's important, since not all these kids will go to college."
