Citing privacy laws, hospital officials didn't reveal any details about the patient but did say they don't believe, at this point, that the patient has potentially-deadly Ebola.
Dr. PJ Brennan, the chief medical examiner at the Hospital of the University of Pennsylvania, said the test for the highly contagious virus is being done out of "an abundance of caution" after the person "met screening criteria for Ebola testing", NJ.com reported.
"Preliminary testing indicates that the patient has another condition, which is likely the cause of their illness", Brennan said in a statement.
The hospital did not release any further information about the identity of the patient or how they were possibly exposed to Ebola.
It is not yet known if the patient had traveled to a location in which the disease is present or otherwise.
Penn says they are following proper protocols and precautions to keep staffers and patients safe. It's thet African country's 10th outbreak and the world's second largest recorded.
The Ebola virus can spread when a person comes into contact with an infected person's bodily fluids - such as blood, urine, stool, saliva or semen - and the fluids enter a healthy person's body through broken skin or mucous membranes, according to the WHO.
On Monday, an global group of public health experts called on the World Health Organization to convene an emergency committee to consider declaring the outbreak an worldwide public health emergency.
