Hepatitis c is a blood borne virus it required blood to blood contact for transmission. Hepatitis c infected blood must enter the blood stream of an uninfected person. Most commonly hepatitis c is transmitted by the sharing of IV drug needles or through blood transfusion prior to 1990 when antibody testing for hepatitis C was developed in the blood supply secured.
The testing process for hep c is to wait at least 12 weeks after a potential blood to blood exposure and then have the hep c antibody test. If that test is positive then a second more expensive test called the HCV RNA by PCR test is performed to look for the presence of the actual virus in the blood. If the HCV RNA test shows detectable levels of the virus the person will likely need treatment to eradicate the hep c virus from their body.
If the person has an HIV infection or otherwise has a compromised immune system like if they are undergoing chemo therapy or taking organ transplant anti rejection meds it can take up to 6 months for hep c antibodies to rise to detectable levels.
For other forms of Hepatitis like hep A or hep B ask in the related forum.
I very much doubt you are at risk of hepatitis c infection based on the situation you have described.
