Antibody to Epstein-Barr nuclear antigen (EBNA), while typically not detectable until six to eight weeks after the onset of symptoms, can help distinguish between acute and previous infections. Very low neutrophil count always look carefully for toxic change and left shift. To test for underlying conditions causing low lymphocyte count, your doctor may order blood tests, lymph node tests, and bone marrow tests. Although the strategy may make sense when used selectively (e.g., when an athlete would like to return to competition in less than four weeks), it cannot be endorsed as routine practice. WebIt is important to differentiate reactive lymphocytes from neoplastic lymphocytes. They may be fewer, but theyre mighty. In addition, evidence of EBV infection is not part of the definition of chronic fatigue syndrome.28 Physicians should be aware of several other rare complications of infectious mononucleosis (Table 4).1,3841. health information, we will treat all of that information as protected health Listeriosis: Symptoms, Causes, Prevention & Kidney Stones: Causes, Symptoms & Treatments.

Platelets, the cells which help with blood clotting, Hemoglobin, the protein in your blood that carries oxygen, Hematocrit, which is the ratio of red blood cells to plasma, the fluid component of your blood, Infectious diseases like tuberculosis, AIDS, and viral hepatitis. The infection is most common in populations with many young adults, such as active-duty military personnel and college students, in whom the annual incidence for infectious mononucleosis ranges from 11 to 48 cases per 1,000 persons.4,5, Infectious mononucleosis is relatively uncommon in adults, accounting for less than 2 percent of all adults presenting with sore throat.6 Family physicians should expect to diagnose one to four patients with infectious mononucleosis per year, depending on the number of adolescents in their practice.3,5 The incidence of infectious mononucleosis shows no consistent seasonal peak.2, EBV is a herpes virus that replicates primarily in -lymphocytes but also may replicate in the epithelial cells of the pharynx and parotid duct.7 The infection is spread primarily by saliva, and the incubation period is four to eight weeks.

Because the physical examination is quite insensitive for detecting splenomegaly (between 27 and 58 percent, depending on the examiners index of suspicion), the absence of splenomegaly should not be used as evidence against the diagnosis of infectious mononucleosis.14.
