Your blood work has answers. The right questions just haven't been asked. You've had labs drawn, maybe more than once, and the response is always the same: everything looks fine. But a number on a page isn't an explanation, and "within range" doesn't mean your body is functioning the way it should. Standard blood work asks one question - is there disease? Functional blood chemistry analysis asks a different one: where is function declining, and what pattern does that point to? A 60-minute 1:1 virtual session with Yelena Tselenchuk, Certified in Functional Blood Chemistry Analysis, reads your existing labs through that functional lens.

You've been told your labs are "normal," and you still don't feel like yourself. You want a deeper read on the results you already have, not a repeat of the same panels with the same answer.
Fatigue, mid-afternoon crashes, or waking unrefreshed despite adequate sleep.
Weight gain or body composition shifts you can't trace to a clear change.
Brain fog, mood shifts, or reduced focus that seems to track with how you're feeling physically.
Digestive issues, cravings, or energy patterns that nobody has connected to your lab results.
Interest in understanding where function is declining before it becomes a diagnosable problem.
This session isn't the right fit if you're looking for a medical diagnosis or prescription, or if you need blood work interpreted in an acute or emergency context. It's educational and consultative by design, not medical care.
Your session covers a thorough review of blood chemistry markers across multiple systems, interpreted through functional optimal ranges rather than the broad disease-detection ranges on most lab reports. Common areas of focus include:
Energy crashes, mid-afternoon fatigue, cravings, and stubborn weight gain often trace back to blood sugar regulation that looks normal conventionally but is functionally suboptimal.
Sluggish metabolism, hair changes, temperature sensitivity, and fatigue can reflect thyroid function that conventional ranges miss. A full thyroid panel evaluated functionally often reveals what a TSH-only screening cannot.
Cholesterol panels read beyond simple high/low flags, including triglyceride-to-HDL ratios and patterns relevant to inflammation and metabolic load.
Cortisol, estrogen, progesterone, and testosterone evaluated through functional ranges. These patterns often contribute to fatigue, mood changes, weight shifts, and sleep disruption that standard interpretation rarely flags.
Chronic low-grade inflammation drives joint pain, brain fog, skin changes, and general malaise, and frequently shows up in blood work that nobody flagged.
Iron, B vitamins, vitamin D, magnesium, and other critical nutrients are often deficient at functional levels even when conventional ranges call them adequate.
Central to detoxification, hormone clearance, and metabolic processing. Patterns here can explain symptoms that seem unrelated on the surface.
Recurrent illness, slow recovery, and autoimmune-adjacent symptoms often leave clues in routine panels that go overlooked when only disease thresholds are applied.
Every marker is read in the context of your symptoms, your history, and how you're actually living. Not in isolation.
How is this different from functional lab testing? Blood chemistry analysis works with blood draws, the type of testing you get at a standard laboratory. It evaluates what's circulating in your bloodstream using tighter, functional reference ranges. Functional Lab Testing expands the investigation into systems that blood alone cannot access: gut microbiome, mycotoxin exposure, hormone rhythms, organic acids, and more, using at-home stool, urine, and saliva collection. Many clients start with blood chemistry analysis as a foundation and layer in functional lab testing when deeper investigation is warranted.
You submit recent blood work drawn within the past 6-12 months for review, or you receive guidance on which panels to order and where to get them drawn. Blood draws are available at local laboratories in all states except New York. Yelena then spends several hours preparing your analysis, reviewing each marker through functional optimal ranges in the context of your symptoms and health history.
Sessions are conducted 1:1 with Yelena Tselenchuk, Board Certified Doctor of Holistic Health (BCDHH), Board Certified Naturopath (BCN), Board Certified Homeopath (BCHP), and Certified in Functional Blood Chemistry Analysis. Her approach is built on investigation rather than reassurance: data and functional markers read in the context of your symptoms, history, and how you're actually living. The goal of the session is clarity - understanding what's driving the way you feel, so you can make informed decisions instead of guessing.
Conventional interpretation compares your results against broad reference ranges designed to flag disease. If your markers fall within range, the report comes back normal. Functional blood chemistry analysis uses narrower, evidence-informed optimal ranges to identify where function is declining, catching patterns that explain symptoms before disease criteria are met. The same panel can tell a very different story depending on what questions are being asked.
Yes. If your blood work was drawn within the past 6-12 months, it can be reviewed during your session. If it's older or if key panels are missing, Yelena will guide you on what to order so nothing important is overlooked.
The right panels depend on your full symptom picture, but a comprehensive functional analysis often includes a complete metabolic panel, complete blood count, full thyroid panel (not just TSH), iron studies, vitamin D, B12, magnesium, inflammatory markers, and blood sugar and insulin markers. A free consultation is the fastest way to confirm exactly what to order for your situation.
Not necessarily, but blood chemistry analysis often provides a strong foundation. It can reveal patterns that help prioritize which functional tests (gut microbiome, hormone panels, organic acids) would add the most value. Many clients start here and layer in additional testing as the investigation unfolds.
Yes. The session is 100% virtual, conducted via Zoom with clients nationwide. Blood draws are available at local laboratories in all states except New York.
Your blood work may already hold the answers you've been looking for. The data just needs to be read with the right questions.
