Test Description
Timothy Grass IgE
Test ID
TIMOTHY
General Information

An allergen is a type of antigen that initiates an immune response. After this initiation, also called sensitization, an allergic individual will produce IgE against that allergen. Specific IgE can be used to determine allergen sensitization, potential anaphylaxis response, and aid in disease management. Assay results should be used in conjunction with clinical findings and other serological tests.
Specimen Type

Serum
Alternate Specimen Type

Plasma (Na-Heparin or EDTA)
Specimen Requirements

Additional Processing Details

Preferred: Centrifuge serum samples (SST, Red Top) within 2 hours of collection.
Alternate: if centrifuging is not possible, uncentrifuged serum samples (SST, Red Top) are acceptable.
Caution: Add-on testing may not be possible on serum samples that are received uncentrifuged. Serum/plasma samples are not to be repeatedly frozen and thawed, since this can cause analyte deterioration. They are to be thawed only once.
