Understand What Your Body Is Telling You

Comprehensive lab testing that looks beyond standard ranges to uncover root causes, identify early imbalances, and guide personalized, evidence-based care—before symptoms become disease.

Advanced Lab Testing for Whole-Body Insight

Functional medicine takes a comprehensive, systems-based approach to understanding health. Rather than looking at labs in isolation or only screening for disease, we evaluate patterns and relationships across multiple body systems to understand how your body is functioning as a whole. Foundational testing often includes advanced blood work to assess metabolic health, inflammation, nutrient status, thyroid and sex hormones, immune function, cardiometabolic risk, and markers of gut and liver health. These labs help us identify subtle imbalances long before they become diagnosable disease and allow for highly personalized treatment plans.

When appropriate, we also incorporate specialty functional medicine testing to gain deeper insight into root causes. This may include salivary or dried urine cortisol testing to evaluate stress physiology and adrenal function, urine-based hormone metabolism testing to understand how estrogen, progesterone, testosterone, and cortisol are being produced and metabolized, comprehensive stool studies to assess the gut microbiome, digestion, inflammation, and infections, or SIBO breath testing to evaluate bacterial overgrowth in the small intestine. We partner with high-quality specialty laboratories such as Precision Analytical (DUTCH), Genova Diagnostics, ZRT Laboratory, and others to ensure accurate, clinically meaningful results. Together, these tools allow us to create targeted, evidence-based strategies that support long-term health, resilience, and optimal performance.

Gentle, Needle-Free Allergy Relief at Home

Sublingual immunotherapy (SLIT), or allergy drops, is less studied and is not covered by insurance. SLIT, however, is easy to administer and rarely has side effects.

We often recommend SLIT for kids or needle-phobic adults.

Sublingual Immunotherapy (SLIT)

Common Questions About SLIT

Sublingual Immunotherapy (SLIT), also known as allergy drops, offers a needle-free, convenient way to treat allergies from home. It’s especially ideal for children or adults who prefer a simpler routine.

No. Despite several published studies demonstrating the effectiveness and safety of SLIT, it does not have FDA approval and is therefore considered “experimental.”

It depends on how severe your symptoms are. Some patients require only a few months, while others may need several years of drops.

Absolutely. SLIT is popular for children because there are no needles or injections. Dr. Pasha limits SLIT to ages over 5 years old.
