Which of the following lab results is not typically associated with acute mononucleosis?

Acute mononucleosis, commonly caused by the Epstein-Barr Virus (EBV), is associated with specific laboratory findings. One of the hallmark features of this condition is lymphocytosis, often accompanied by the presence of atypical lymphocytes. These atypical lymphocytes are typically larger than normal lymphocytes and have a distinct morphology, reflective of the immune response to the viral infection.

The presence of positive EBV titers, particularly for IgM and IgG, is also highly relevant in diagnosing acute mononucleosis. IgM antibodies indicate a recent infection, while IgG suggests either past infection or reactivation.

Elevated liver function tests are commonly seen in acute mono due to liver involvement with the virus, and it can result in mild hepatitis, corroborating the systemic nature of the disease.

Elevated creatinine and blood urea nitrogen (BUN) levels are not typical findings associated with acute mononucleosis. These results suggest possible renal impairment or dysfunction, which is not characteristic of the disease itself. Therefore, while options A, B, and C align with the expected laboratory results for mononucleosis, the elevation of creatinine and BUN is not commonly associated with this condition.

In summary, the correct
