Allergen, Weed, Sheep Sorrel
Also known as: SHEEP SORR
Use
The test measures specific IgE antibodies to the allergen Sheep Sorrel, part of the weed family, in human serum. This helps in evaluating allergic response or sensitization in patients who may present symptoms of allergy. The quantitative measurement is useful in understanding the magnitude of sensitization, but its clinical relevance must be correlated with the patient's clinical history and other investigations.
Special Instructions
Multiple patient encounters should be avoided for accurate testing. Serum should be separated from cells as soon as possible or within 2 hours of collection. The test is New York state approved.
Limitations
Allergen results in the range of 0.10-0.34 kU/L have an undetermined clinical relevance and should be interpreted by specialists. The concentrations may not correlate with clinical response or skin testing results. A negative result does not eliminate the possibility of clinical allergy or anaphylaxis. The test is limited by hemolyzed, icteric, or lipemic specimen conditions which are deemed unacceptable.
