Overview

There are no diagnostic lab findings associated with lymphangitis. The presence of certain non-specific laboratory findings, in the presence of lymphangitis, may be suggestive of certain underlying causes. Examples of tests that may demonstrate abnormal findings include CBC, ESR, CRP, and serology titers.

Laboratory Findings

There are no diagnostic lab findings associated with lymphangitis The presence of certain non-specific laboratory findings, in the presence of uveitis, may be suggestive of certain underlying causes. Routine laboratory studies should be correlated with a carefully collected history and a precise physical examination. Routine laboratory tests that may be ordered and their respective findings include:

Complete Blood Count with Differentials and Peripheral Blood Smear

• Eosinophilia may be suggestive of underlying parasitic infections.
• Elevated white blood cells with a left shift may be suggestive of an underlying infection.
• Microfilariae on Giemsa stained, thin and thick blood film smears, are considered gold standard in diagnosis for Filariasis

ESR and CRP

• Elevated ESR and CRP may be suggestive of an underlying infection or inflammatory condition

Serology tests

• F. tularensis titre
• Histoplasma titre

Microbiological investigations

• Swab and aspirate taken from the primary site, should be sent for microscopy as well as cultural and sensitivity.
• Microbiological investigations not only helps us to identify causative infectious organism, but also act as a guide to select appropriate antimicrobial

Other Laboratory Findings

• Rarely, Polymerase chain reaction(PCR) can be used in diagnosis of Nocardia, Tularemia, and Leshmania.
