White Mulberry (T70) IgE Biomarker Testing
It measures IgE antibodies to white mulberry to assess allergy sensitization, with convenient ordering and clear results through Vitals Vault and Quest.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
A White Mulberry T70 IgE test is an allergy blood test that looks for IgE antibodies your immune system may make in response to white mulberry (Morus alba) allergen exposure.
This test does not “prove” you will react every time you encounter mulberry. Instead, it helps show whether you are sensitized, which is one piece of the puzzle alongside your symptoms, timing, and exposures.
If you are trying to sort out seasonal nasal symptoms, asthma flares, or unexplained hives, a targeted specific IgE test can help you and your clinician decide what to avoid, what to treat, and whether broader allergy testing makes sense.
Do I need a White Mulberry T70 IgE test?
You may consider White Mulberry (T70) IgE testing if your symptoms reliably show up during certain seasons or after outdoor exposure and you suspect tree pollen is a trigger. Common patterns include sneezing, itchy or watery eyes, nasal congestion, post-nasal drip, cough, wheezing, or worsening asthma control.
This test can also be useful if you have recurrent hives (urticaria) or itchy skin and you are trying to rule in or rule out an environmental allergy component, especially when symptoms track with time outdoors or windy days.
You usually get the most value when you can name a likely exposure and a timeframe. If your symptoms are year-round, you may need a broader inhalant allergy workup (multiple trees, grasses, weeds, dust mites, molds, and animal dander) rather than a single allergen.
Testing supports clinician-directed care and shared decision-making. Your result should be interpreted with your history, exam, and any other labs, rather than used as a standalone diagnosis.
This is a laboratory-developed specific IgE blood test performed in a CLIA-certified lab; results indicate sensitization and must be interpreted in clinical context.

Key benefits of White Mulberry (T70) IgE testing
- Helps identify whether white mulberry is a plausible trigger for seasonal allergy symptoms.
- Supports targeted avoidance planning when symptoms worsen outdoors or during tree pollen season.
- Adds objective data when deciding between blood testing and skin testing with an allergist.
- Helps distinguish “sensitization” from other causes of congestion, cough, or itchy eyes.
- Can guide whether you should broaden testing to related tree pollens or mixed inhalant panels.
- Provides a baseline value that can be trended if you start or adjust allergy treatment plans.
- Pairs well with PocketMD to translate the lab number into practical next steps for your situation.
What is White Mulberry (T70) IgE?
White Mulberry (T70) IgE is a “specific IgE” blood test. It measures the amount of immunoglobulin E (IgE) antibodies in your blood that recognize proteins from white mulberry (Morus alba). IgE is the antibody class most closely linked to immediate-type allergic reactions.
A positive result means your immune system has made IgE that binds to white mulberry allergen extracts used in the test. That is called sensitization. Sensitization can be associated with symptoms, but it is not the same thing as a confirmed clinical allergy.
White mulberry is commonly discussed in the context of environmental exposure (pollen) rather than food reactions. If you suspect reactions to foods, your clinician may recommend testing directed at those specific foods and considering cross-reactivity patterns.
Sensitization vs. allergy symptoms
You can have a detectable specific IgE and still have mild or no symptoms, especially if exposure is low. On the other hand, you can have classic allergy symptoms with a negative result if a different allergen is responsible or if non-allergic conditions (like viral infections, irritant rhinitis, or reflux) are driving symptoms.
How this test fits into an allergy workup
Specific IgE testing is most useful when it matches your story: timing, location, and exposures. If your symptoms are seasonal, pairing this test with other local tree pollens can help you identify the most likely culprits. If symptoms are persistent, a broader inhalant panel may be more efficient than ordering single allergens one at a time.
What do my White Mulberry (T70) IgE results mean?
Low or undetectable White Mulberry (T70) IgE
A low or undetectable result makes white mulberry sensitization less likely, but it does not automatically explain your symptoms. You may be reacting to other pollens (other trees, grasses, weeds), indoor allergens (dust mites, pets, molds), or non-allergic triggers like smoke, fragrances, or temperature changes. If your symptoms are strongly seasonal, consider testing a broader set of regionally relevant pollens rather than stopping at one negative result.
In-range White Mulberry (T70) IgE
For specific IgE tests, “in range” typically means below the lab’s positivity cutoff. In practical terms, that usually points away from white mulberry as a meaningful driver of symptoms. If you still feel worse during tree pollen season, your clinician may look at other tree allergens, total IgE, eosinophils, or consider conditions that mimic allergies, such as chronic sinus inflammation or non-allergic rhinitis.
High White Mulberry (T70) IgE
A high result suggests you are sensitized to white mulberry, which can support an allergy explanation when your symptoms line up with exposure. The number alone does not predict how severe your symptoms will be, and it does not guarantee you will react every time. Your clinician will typically interpret this alongside your symptom pattern, any asthma history, and results for other pollens to see whether mulberry is a primary trigger or part of a broader tree pollen sensitization profile.
Factors that influence White Mulberry (T70) IgE
Your result can be influenced by the timing and intensity of exposure, since some people see higher values during or after peak pollen seasons. Cross-reactivity can also play a role, where IgE made to one tree pollen binds to similar proteins in another, which can make it harder to pinpoint a single culprit. Medications like antihistamines generally do not suppress blood IgE results the way they can affect skin testing, but immune-modifying therapies and certain medical conditions can change your overall allergic inflammation. Lab methods and reporting thresholds vary, so it helps to trend results at the same lab when possible.

Frequently Asked Questions
What does the White Mulberry T70 IgE test measure?
It measures allergen-specific IgE antibodies in your blood that bind to white mulberry (Morus alba) proteins. This indicates sensitization, which may or may not match your real-world symptoms.
Do I need to fast for a White Mulberry (T70) IgE blood test?
Fasting is not typically required for specific IgE testing. If you are combining it with other labs (like lipids or glucose), follow the fasting instructions for the full order.
Is a positive White Mulberry IgE the same as having an allergy?
Not exactly. A positive result means your immune system has made IgE that recognizes white mulberry, but an allergy diagnosis depends on whether exposure triggers symptoms and how consistent that pattern is. Your clinician may also consider skin testing or supervised exposure history when needed.
Can antihistamines affect my White Mulberry IgE result?
Antihistamines usually do not significantly change blood specific IgE results. They can interfere with skin testing, which is one reason blood testing is sometimes chosen when you cannot stop allergy medications.
How often should I retest specific IgE to white mulberry?
Retesting is most useful when it will change a decision, such as clarifying a confusing pattern, monitoring a broader allergy plan, or reassessing after a meaningful change in exposures. Many people do not need frequent repeats; a common approach is to reassess seasonally or annually if symptoms and management plans warrant it.
What other tests should I consider if my White Mulberry IgE is high?
You may benefit from testing other tree pollens common in your region and considering total IgE and a complete blood count with eosinophils if your clinician is evaluating allergic inflammation more broadly. If asthma is part of your picture, lung function testing and an asthma-focused plan are often more actionable than chasing a single allergen number.
