Lymphocyte to monocyte ratio as a screening tool for influenza
نویسندگان
چکیده
In fall 2009 the emergency department of a clinic in Greece with increased patient visits due to influenza-like illness observed a particular pattern in the complete blood count (CBC) of these patients. In 90% of all patients with probable influenza, lymphopenia and/or monocytosis were present. Relative lymphopenia with or without monocytosis appears to be a laboratory marker for H1N1 virus infection, a finding that could play a major role in early identifying and treating patients with new influenza A. A ratio of lymphocytes to monocytes below 2 is proposed as a screening tool for influenza infection instead of rapid tests.

Background: Low vitamin D has been linked to enhance inflammatory markers in various pathological conditions. We aimed to evaluate the urinary tract infection (UTI)-associated hematological and inflammatory markers mediated by low serum levels of 25-hydroxyvitamin D [25(OH)D]. Methods: Vitamin D level, hematological indices (Neutrophil-to-lymphocyte ratio [NLR], Monocyte-to-lymphocyte ratio [M...
