What Is Cat Scratch Fever?
8. CSD Diagnosis
Cat scratch disease displays symptoms that are common to other infections. A physical examination of the patient and an assessment of symptoms and history provide a good indication of whether a diagnosis of CSD is warranted.
A blood test may be ordered to verify the presence of B. Henselae. The bacteria’s presence can be determined with a polymerase chain reaction test. This is likely to be done only in more serious cases or when the potential for an alternative diagnosis is strong.
