Safflower (Carthamus tinctorius) IgE
Use
The Safflower (Carthamus tinctorius) IgE test is used to detect specific IgE antibodies to safflower in the serum. This can help in the diagnosis of safflower allergy in individuals showing symptoms of allergic reactions, such as hives, asthma, or anaphylaxis, after exposure to safflower. This test is especially significant for patients who require identification of specific allergens to guide avoidance strategies and treatment plans, including potential desensitization therapies.
Special Instructions
Specimen collection requires a plain red-top tube or serum gel tube. After drawing blood, it must be spun down and 0.5 mL of serum should be sent refrigerated in a plastic vial. Preferred stability is refrigerated for up to 28 days, but samples can also be kept frozen for up to 365 days to maintain viability.
Limitations
The test may not detect safflower allergy in individuals with low IgE levels or in those with non-IgE-mediated allergic reactions. False positives can occur due to cross-reactivity with other allergens. High lipemic samples may interfere with the test, leading to inaccurate results and are subject to rejection. It is important to correlate results with the patient's clinical presentation and history.
