Lab Tests For A Patient With Fever : How To Remember Easily ?
L – Low-grade fevers or suspected occult disease benefit from measuring C-reactive protein (CRP) level and erythrocyte sedimentation rate, as they are valuable markers of inflammatory processes.
A – A complete blood count should be included in the workup, and a differential count should be performed to identify juvenile or band forms, toxic granulations, and Döhle bodies, which suggest bacterial infection.
B – Blood count may reveal neutropenia in viral infections.
T – The measurement of circulating cytokines such as IL-1 and TNF is often not helpful in patients with fever since their levels in the circulation can be below the detection limit or do not coincide with fever.
E – Elevation of CRP levels is induced by IL-6, which can be measured and is useful during febrile disease.
S – The most valuable measurements for detecting occult disease in patients with low-grade fevers or suspected occult disease are the C-reactive protein (CRP) level and erythrocyte sedimentation rate.
