With the Transit Card, the only difference was that the rapid transit fare deduction would be $2.00. The cash fare on buses would increase to $2.00, with transfers no longer available. The CTA's last fare increase in 2009 was $2.25 on trains, with $2.00 the fare on buses.
Testing For Diarrhea. To test for potential causes of diarrhea, a stool sample must be collected. A small amount of the stool should be collected in a sterile container to prevent contamination. This can be done at your primary care provider's office, urgent care, or at an emergency room if the condition has become severe.
Tests may include: 1  Blood test(s)- to check for infection and inflammation or other cause of symptoms such as celiac disease. 2  Stool sample- to check for parasite infections and hidden blood. 3  Lactose breath hydrogen test- to find out if you have trouble digesting milk products.  Abdominal x-ray- to check internal organs.
