It's a big health concern surrounding a health fair in Temple on August 25th.
Scott & White Hospital said the same lancet was possibly used on multiple people for glucose testing.
Texas A&M medical students were performing the tests.
They were being supervised by a Health Science Center faculty member who is also a doctor at Scott & White.
Scott & White has responded to the incident.
They're contacting people who attended the "HealthFest 2012" so the people who attended can receive free blood testing.
The hospital said steps are being taken to put processes in place to minimize the likelihood of future incidents like this.
According to Texas A&M Health Science Center, 20 glucose tests may have involved a previously used lancet.
One woman who attended the HealthFest with her son and received the glucose test, said she was called and told she needed to come in twice for blood testing.
She said she felt something wasn't right after she received the initial test.
"He said that a lot of the people were used by the same needle and I'm like what? He said it was a mistake, well I'm like that means that I'm in worries of AIDS and HIV," said glucose test patient Stephanie Penny.
"I think that the organization that offers the testing is doing it for very thorough situations. The chance of something happening with this is very very low, probably less than one percent risk," said Dr. Tim Martindale.
Scott & White released this statement:
"As a precaution to all concerned, we are contacting anyone who attended the event and had glucose tests performed, to provide an opportunity for free blood testing at Scott & White."
If you did attend the event and had a glucose test, you can call Scott & White at (254) 724-0241 for more information and to schedule your screening.
