Allergy Testing

We offer various tests to find the root cause of your symptoms.

Systemic Chronic Inflammation, Allergies, and Autoimmunity

Systemic Chronic Inflammation caused by allergies, microorganisms, pathogens, environmental and food substances can result in body, muscle, and joint pain as well as fatigue, depression, anxiety, weight gain, brain fog, and gastrointestinal problems (constipation, diarrea, acid reflux and bloating). It can progress, or worsen, other disorders such as Polycystic Ovarian Syndrome (PCOS), Arthritis, Heart Disease, Diabetes, Asthma/Allergies, Dementia and Obesity.

Left untreated, your immune system can become “hyperactive”, attacking healthy cells, resulting in autoimmune reactions, or may over-respond to low-grade stimuli resulting in a neverending cycle of the aforementioned symptoms and/or excerbation of:

Other Associated Conditions related to Allergies
Sleep Apnea/Snoring, Irritability, Migraines, Canker Sores, Hair Loss/Alopecia, Frequent Sinus/Ear Infections, Gastritis/Acid Reflux, Frequent Colds/Bronchitis, Dizziness, Dark Circles Under Eyes, Shortness of Breath, Wheezing/Coughing.

We offer various tests to find the root cause of your symptoms. You may need one or a few based on your symptoms and history.

Testing Available

Skin scratch tests involve applying known allergens directly to your skin using an applicator with pricked tips on your arm. This test is useful in determining acute allergic reactions to environmental (animals, dust, plants, molds, and weeds) and food sources. Developing a small bump at the site of application is a positive indication that the substance is an allergy trigger. We will carefully monitor your health throughout the skin allergy test. Results are available immediately after testing.

Blood tests may be used to isolate microorganisms, substances, or toxic materials and/or antibodies that are produced when you make contact with an allergen.

Testing for the presence of IgG antibodies is useful for individuals who suspect that a food is responsible for causing their symptoms. The presence of circulating IgG antibodies to foods may also be suggestive of increased intestinal permeability, also referred to as “leaky gut syndrome”, resulting in a greater immune response. Your blood will be drawn in our office and will take 1-2 weeks to process

Poor eating habits, medications, stress, smoking, and more can encourage the growth of unhealthy bacteria triggering a cascade of inflammation resulting in systemic chronic health issues such as weight gain, diabetes, heart disease, high blood pressure, cancers, and more.

Comprehensive stool tests, are collected at home, and provides valuable information about digestion, inflammation, and bacterial overgrowth to identify the source and possible diagnosis to explain your symptoms such as pancreatic exocrine insufficiency, inflammation, food allergies, harmful organisms. Results are available within 1-2 weeks.

Blood and urine samples are collected to assess functional, metabolic and nutritional status to  identify root causes of dysfunction and provide a systems-based approach overcome chronic conditions.  You will be provided with personalized vitamin and nutritional recommendations to support immune balance based on your results within 1-2 weeks.


Determining your triggers, or cause of your symptoms, can help us figure out how to best treat your condition.  We will discuss treatment options, including dietary changes, avoidance, lifestyle management, supplements, medication, immunotherapy (“allergy shots”), or low dose antigen therapy if appropriate.  You will be provided with a personalized care plan including strategies to control your symptoms and prevent further progression.

Harmony in Health: Your Primary Care and Wellness Experts

For more than a decade, Harmony in Health has provided primary care and wellness services to the Northern Virginia area. Led by NP Jessica Hardy, MSN – BC, our dedicated care team has supported thousands of patients to living happier, healthier lives- and are ready to help you.

I was seen by Jessica and she is just the sweetest provider I have come across. She is very attentive, gentle and knows her stuff. Her staff compliments her environment as they are just as humble. I have lost alot of weight with Jessica's dietary plans and supplements. She even took me away from being "borderline diabetic". My health has changed drastically since coming to see her. I would recommend her to anyone!!!

ED Designation

I've struggled with my weight for most of my adult life and have been on any number of diet and fitness plans without lasting success. This year, I decided it was truly time to shed the weight and keep it off so I reached out to Harmony in Health for their help. Jessica helped me design a program that would work for me, kickstart my weight loss, and help improve my overall health. After only a month on a custom weight loss plan Harmony in Health designed for me, I had lost 23 pounds! The best part was that my DEXA scans showed that initial loss was all fat and my labs showed marked improvement. Sticking with a very structured plan wasn't easy but the support and encouragement of Jessica and the Harmony in Health team really made a difference in helping me move ever closer to my wellness goals. I highly recommend working with Jessica and her team, especially for those that have tried and failed with lasting fat reduction/weight loss plans in the past.


Not only have I succeeded in a substantial amount of weight loss (I thought was impossible to lose), Jessica has helped me with many other medical issues!


I have rarely encountered health care professionals with Nurse Practitioner Hardy's level of personal care. She has been committed to helping me find solutions to chronic health care problems, and for the inflammation, metabolic dysfunction and subsequent weight gain. NP Hardy has worked with me tirelessly through a complex health history and her approach finally has me feeling and looking healthier for the first time in ages!
