What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

Coxiella burnetii phase 1 and 2 IgG and IgM panel - Serum

Coxiella burnetii phase 1 & 2 Ab.IgG & IgM panel

This panel combines assays for phase 1 and 2, IgG and IgM antibody testing, for diagnosing past and present Q fever infections caused by Coxiella burnetii. Coxiella burnetii is a species of intracellular, pathogenic bacteria, and is the causative agent of Q fever. The genus Coxiella is morphologically similar to the rickettsia, but with a variety of genetic and physiological differences. C. burnetii are small Gram negative bacteria with two growth phases, as well as a spore form which lies idle in soil. It can survive standard disinfectants, and is resistant to many other environmental changes. PathogenesisThe ID50 (the dose need to infect 50% of experimental subjects) is one via inhalation i.e. inhalation of one organism will yield disease in 50% of the population. Disease occurs in two states: An acute state presents with headaches, chills, and respiratory symptoms, and an insidious chronic stage. While most infections clear up spontaneously, treatment with tetracycline appears to reduce the symptomatic duration and reduce the likelihood of chronic infection.
