Clinical Utility The QUANTIA Immunoglobulin E (IgE) immunoassay is intended for the quantitative determination of immunoglobulin E in human serum or plasma on the ARCHITECT cSystems (i.e. c4000, c8000, and c16000) and the AEROSET System. The assay is intended for use in clinical laboratories. The measurement of IgE is useful in the clinical diagnosis of IgE-mediated allergies. IgE antibodies are allergic, homocytotropic, anaphylactic, reaginic, atopic, and skin-sensitizing antibodies.

Clinical Utility IgE antibodies are the chief immunoglobulin responsible for immediate hypersensitivity reactions in humans. There is a certain correlation between chronic allergen exposure and the level of total IgE. Verification of diagnosis can only be performed by appropriate in vitro and in vivo diagnostic tests. The measurement of IgE is indicated in diagnosing allergies, extended investigation of allergies, illnesses associated with eosinophilia or fever of unknown origin, congenital immunodeficiency syndromes and acquired immunodeficiency syndromes.

QUANTIA IgE Reaction Methodology
Step 2: Reagent 2 containing latex particles coated with mouse anti-human IgE is added to the sample/Reagent 1 mix Step 1: Sample containing IgE is added to Reagent 1 (Reaction Buffer) Sample/ Reagent 1 Reagent 2 ↑ IgE ↑ IgE Specific Antibody ↑ Latex <200nm Diameter Step 3: When sample containing IgE is added to R1 and mixed with the antibody in R2 insoluble aggregates form. The degree of agglutination is directly proportional to the concentration of IgE in the sample. This is determined by measuring the decrease of transmitted light caused by the aggregates at a wavelength of 572.

QUANTIA Immunoglobulin E Calibration
Calibration is stable for 30 days (720 hours) and is required with each change in reagent lot number. Use the QUANTIA IgE Calibrator K50-02 Calibration: The assay must be calibrated using a full calibration (6 point calibration) procedure by using a water blank and the five levels of QUANTIA IgE Calibrator.

QUANTIA Immunoglobulin E Calibration
Do not freeze calibrators. The calibrators are prepared with purified human IgE in a Hepes buffer. Calibrator values are determined over multiple runs against Calibrator House Standards which are traceable to the 2nd WHO International Reference Preparation of Human Serum Immunoglobulin E (IgE) code 75/502. The concentration of the calibrators are indicated on the vial labels in IU/mL. Calibrators are liquid ready to use and stable until the expiration date indicated on the package when stored at 2-8 °C.

QUANTIA Immunoglobulin E Quality Control
Do not freeze controls. The controls are prepared from human sera containing ferritin, myoglobin, and IgE. The control concentrations are indicated on the corresponding control value sheet. The lyophilized control should be reconstituted with 3.0 mL of deionized water or equivalent. The lyophilized controls are stable until the expiration date on the label if stored at 2-8 °C. Once reconstituted, the controls can be used for 15 days if stored between 2-8 °C.

QUANTIA Immunoglobulin E Performance Data
Serum and Plasma Reportable Range: 25.0 to IU/mL 25.0 to IU/mL using the on-board dilution protocol Limit of Quantitation (LOQ) = 25.0 IU/mL LOQ represents the lowest measurable concentration at which the within-run CV < 20% and the recovery is within +/- 20% of expected value. Limit of Detection (LOD) = 12.9 IU/mL LOD is defined as the mean concentration of an analyte-free sample + 2SD, where SD is the within-run standard deviation.

QUANTIA Immunoglobulin E Performance Data
Expected Values: In clinically healthy subjects the serum IgE levels exhibit a wide distribution range and do not follow a normal distribution. Age related concentrations must be taken into account when interpreting IgE values in children. IgE does not cross the placental barrier so IgE is not detectable in neonates. The IgE concentration increases during the first year of life, reaching a peak at years and dropping subsequently in adults. Reported Expected Range (varies with age and sex): 1 - 5 yrs < 60 IU/mL 6 - 9 yrs < 90 IU/mL 10 – 15 yrs < 200 IU/mL Adults < 100 IU/mL Source(s): Quantia IgE 6K42 Package Insert Ringel KP, Dati F, Buchholz, E.

QUANTIA Immunoglobulin E Performance Data
Reported Expected Range: 1 - 5 yrs < 60 IU/mL 6 - 9 yrs < 90 IU/mL 10 – 15 yrs < 200 IU/mL Adults < 100 IU/mL Note the expected range starts at age 1 year. This method should not be used for testing children less than the age of 1 year. Reason(s): Patients younger than 1 year typically have results lower than this method’s Limit of Quantitation- LOQ (25 IU/mL). Results lower than LOQ will have too much imprecision for clinical use.
