GWINNETT COUNTY, Ga. -- The results are in from skin tests administered at a Gwinnett County school after an 11th-grade student came down with a suspected case of tuberculosis (TB).

Gwinnett County school spokeswoman Sloan Roach confirmed to WSB-TV that 25 of the 175 tests administered at Meadowcreek High School came back with positive results.

Roach said the positive test results don't indicate whether those tested actually have the disease, but said it means they came in contact with someone who did.

Roach said none of the individuals showed signs or symptoms of having the disease, but that health care officials are asking them to have chest x-rays, the normal process for a positive skin test.
