"Scorpion" season 2, episode 19 will see Team Scorpion dealing with a blood contamination case.
In the teaser released by CBS for "Ticker," Agent Cabe Gallo (Robert Patrick) will inform his team of what they should do to help stop the contamination being done by only one person.
"Guys, we just received a disturbing email," Cabe said.
"Two places and two other hospitals were diagnosed with... Both had blood transfusions," the guest star said.
"All area hospitals get their blood from the county depository blood bank," Toby (Eddie Kaye Thomas) said.
"So it isn't just this place? There's a system wide contamination of the whole inventory..." Walter (Elyes Gabel) said.
"Dr, you just parted your lips..." Toby noticed.
"As blood bank supervisor for the hospital, I work closely with the depository..." the doctor said.
"So somehow the diseased research blood got mixed in with the healthy blood?" Sylvester (Ari Stidham) asked.
"That's the thing. All the labels on the blood banks here have barcodes. They were labeled safe," the doctor explained.
"So there's no way of knowing which blood banks have virus anywhere in the country getting a transfusion can get infected," Paige (Katharine McPhee) said.
"What if we test all the blood and see which is safe to use?" Cabe suggested.
"Those tests take 12 hours, and a test can only be done on someone who was already infected because the viral loads higher when it's already incubated," Toby answered.
"Cabe, you need to get homeland to shut down the entire L.A. blood supply until it can get tested. No surgeries, no transfusions, nothing," Walter said.
"Can we get clean blood from a blood drive?" Paige asked.
"You can't replace 25,000 units of blood with a blood drive and if the hospital tries to buy blood from a blood bank it will take days to get here," Toby said sarcastically.
"Mixing up labels is gonna result in people dying," Happy (Jadyn Wong) said.
Meanwhile, the doctor revealed an information he just received via email.
"The hospital just sent an email..." he said.
The doctor confirmed that the contamination of blood was done intentionally.
