The antibody response to Legionella may be detected 4 days
to 6 weeks after exposure and may remain elevated for months
or years. Thus, a fourfold or greater rise in titer is required to confirm
a diagnosis of current infection. Serologic testing does not usually
allow definitive differentiation of Legionella serogroups.
Mycoplasma Pneumoniae IgG and IgM Antibody, IFA (Serum)
Reference Range: IgG < 1:64
IgM < 1:32
M. pneumoniae is an important cause of community-acquired
pneumonia. The incubation period is from 2 to 3 weeks and primary
infection usually occurs in children and young adults. Reinfection
accounts for most cases in patients over 45 years and may be
associated with severe symptoms. Laboratory diagnosis of M.
pneumoniae infection is important so that appropriate antibiotic
treatment may be initiated.
IgG titers equal to or greater than 1:64 and/or IgM titers equal to
or greater than 1:32 usually suggest recent infection.

Aureobasidium pullulans, IgE
Clinical Information: Clinical manifestations of immediate hypersensitivity (allergic) diseases are
caused by the release of proinflammatory mediators (histamine, leukotrienes, and prostaglandins) from
immunoglobulin E (IgE)-sensitized effector cells (mast cells and basophils) when cell-bound IgE
antibodies interact with allergen. In vitro serum testing for IgE antibodies provides an indication of the
immune response to allergen(s) that may be associated with allergic disease. The allergens chosen for
testing often depend upon the age of the patient, history of allergen exposure, season of the year, and
clinical manifestations. In individuals predisposed to develop allergic disease(s), the sequence of
sensitization and clinical manifestations proceed as follows: eczema and respiratory disease (rhinitis and
bronchospasm) in infants and children less than 5 years due to food sensitivity (milk, egg, soy, and wheat
proteins) followed by respiratory disease (rhinitis and asthma) in older children and adults due to
sensitivity to inhalant allergens (dust mite, mold, and pollen inhalants).
Useful For: Testing for IgE antibodies may be useful to establish the diagnosis of an allergic disease
and to define the allergens responsible for eliciting signs and symptoms. Testing also may be useful to
identify allergens which may be responsible for allergic disease and/or anaphylactic episode, to confirm
sensitization to particular allergens prior to beginning immunotherapy, and to investigate the specificity of
allergic reactions to insect venom allergens, drugs, or chemical allergens.
Interpretation: Detection of IgE antibodies in serum (Class 1 or greater) indicates an increased
likelihood of allergic disease as opposed to other etiologies and defines the allergens that may be
