Which of the following tests cannot normally be done in primary care?

In primary care, X-ray imaging typically cannot be performed on-site due to the need for specialized equipment and safety protocols associated with radiation exposure. Most primary care facilities are not equipped with X-ray machines, and patients usually need to be referred to a radiology department or an imaging center to have an X-ray conducted.

In contrast, blood tests, urine tests, and physical examinations are standard procedures that can be conducted in a primary care setting. Blood tests and urine tests can often be performed on-site, with results either available immediately or within a short timeframe. Physical examinations are fundamental components of primary care visits, allowing healthcare providers to assess a patient's overall health and identify potential issues during a routine consultation.
