Hickory Shagbark (Carya ovata) IgE
Use
The Hickory Shagbark (Carya ovata) IgE test is used to detect the presence of specific IgE antibodies in the serum, indicating a possible allergic reaction to Hickory Shagbark. This test helps in diagnosing allergic diseases related to the exposure of Carya ovata and can assist in the management and decision-making process for treatment of patients with suspected IgE-mediated hypersensitivity.
Special Instructions
Ensure that the blood is collected in a plain red-top tube, though a serum gel tube is also acceptable. After drawing, the sample should be spun down, and 0.5 mL of serum should be sent in a plastic vial, refrigerated. The preferred temperature for transport and storing this test is refrigerated, although ambient conditions for up to 28 days and frozen conditions for 365 days are also acceptable.
Limitations
The test is specific to IgE antibodies linked directly to Hickory Shagbark (Carya ovata) and is thus limited to diagnosing hypersensitivity reactions related to this specific allergen. It cannot detect non-IgE-mediated allergies or other types of hypersensitivities that may be present. The presence of lipemia in the specimen can lead to rejection. As this test has not been cleared or approved by the FDA, it limits the use to contexts where FDA approval is not a requirement for clinical decisions.
