The history picks the first lab
The visit starts with a timeline. When the symptom started, what else changed, what has already been tested, and what you are afraid is being missed. That timeline points at a system. Hormones, gut, metabolism, or an exposure each suggest a different specimen. Functional lab testing is the decision, not a product. Dr. Tara Kohen says the question in a sentence before any kit is named.
Prior records change the decision. A thyroid panel from last month is not redrawn for atmosphere. A stool test done in the middle of antibiotics may need to be set aside. Bringing results is part of the exam. A free 20-minute consultation can be enough to learn that you do not need a new lab yet. That is a successful consult.
DUTCH, stool, blood, or breath
DUTCH hormone testing fits a question about sex hormones, metabolites, and the shape of cortisol across a day. It is dried urine at home. It is a poor tool for a thyroid dose decision, which wants blood. GI-MAP stool testing fits a question about organisms, digestion markers, and inflammation such as calprotectin. It does not draw a breath-gas curve.
A breath test fits a question about hydrogen and methane after a substrate, with a prep diet and a long morning. Bloodwork fits glucose, insulin, iron, B12, lipids, or thyroid hormones. Chronic fatigue might lead to any of these, or to none, depending on the timeline. Hormonal imbalance does not automatically mean DUTCH if the story is actually a thyroid medication problem. The specimen follows the story.
Ordering less on purpose
Each lab creates pages that demand attention. Ordering four kits on day one produces a review that skims. It also confuses cause: you cannot tell which change mattered. FRI sequences. One lab, a decision, then another only if the first left a defined hole. Dr. Sani Kohen will tell you which popular test is being skipped. The skip is part of the plan.
Brain fog and gut health together still do not justify a stack. If the gut story is louder, stool or breath comes first. If the hormonal story is louder, urine or thyroid blood comes first. The second test waits until the first has been read. Patience here is cheaper and clearer.
The extra cost, said before the kit
Labs are an additional cost on top of the clinical visit. The amount depends on the lab and the panel, and this page will not invent a number. You should hear, in the room, that there is a separate fee and what has to be true for the fee to be worth it. HSA and FSA cards can be used for many of these expenses. The office is out of network and provides a superbill for the visit. Reimbursement is between you and your plan.
The review of results is its own visit and often runs 30 to 60 minutes depending on the plan. You are not emailed a highlighted PDF as the whole interpretation. If the result is urgent, you hear sooner. If the result changes nothing, you hear that too. A lab that changes nothing was still a decision, and the next one is harder to justify.
What a Functional Lab Testing visit is like
Expect more questions than vials at the first visit. You will talk through sleep, cycle, bowel pattern, diet, buildings, work exposures, and prior tests. The end of the visit is either one lab with a reason, a request for records, or a decision to wait. Leaving with three kits is the exception and needs an unusually clear set of separate questions.
When results return, the review ties them back to the sentence that ordered them. Unrelated abnormalities are not hunted for sport. Anything that belongs with a physician is handed off in plain language. You should be able to say which test you did not do, and why.
405 to the 73
Take the 405 south to the 73 toward Mission Viejo, then to La Alameda. About 20 miles and 30 to 45 minutes. The address is 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Park at the building. Hours run Monday through Thursday, 9 to 6. Leaving Fountain Valley after 4 and expecting a calm neck exam is optimistic. Book earlier.
Phone (949) 312-1754. The complimentary consultation is 20 minutes. Use it if the drive makes you want a smaller first commitment. If you already know you want testing, book the evaluation so we are not talking in circles.
Techniques and medical problems we will and will not own
Neurodynamics and McKenzie Method care are central for nerve and disc patterns. Gait analysis earns its place when the Mile Square loop and the sidewalk tell different stories. Cupping is a decompression tool, not a detox.
We also see metabolic syndrome and diabetes questions beside the physician who manages medication. We do not change those drugs. The city page is the Fountain Valley chiropractor page.
Payment
Out of network. Superbill. HSA and FSA. No referral. Bring a medication list if you want labs or if you are here for a systemic symptom. Imaging is helpful and not required for every back pain visit.
Drs. Sani and Tara Kohen are on the about page. The building is on the office page.
Mile Square, a flat grid, and long freeway days
Fountain Valley is flat, which sounds simple and is not. Mile Square Park gives people a long, level loop for walking and cycling. The rest of the city is a grid of Slater, Brookhurst, and Euclid: short drives, a lot of sitting, and jobs that may be in the city or up the 405. A flat park loop is a clean test of walking tolerance. Pain that waits until the car, not the loop, points us at sitting and at the spine rather than at a hill that does not exist here.
Low back pain and sciatica are evaluated with that distinction. Neck pain often belongs to the 405. Knee pain in cyclists around Mile Square gets a bike-and-hip history, not a generic brace.
Questions patients ask
Why not order DUTCH, stool, blood, and breath together?
They answer different questions. Running all of them at once blurs which result matters and spends money before the history has earned it. One lab is sequenced before the next.
How much do the labs cost?
They are an additional cost beyond the visit, and the figure depends on the test. FRI will not quote a made-up price here. You are told there is a separate fee before you order.
Do I need labs to start care?
No. Many mechanical problems need an exam and treatment, not a kit. Functional labs are for questions the history cannot answer by looking and moving.
What if my results are normal?
Normal is an outcome. It closes that question and makes the next kit harder to justify. The visit says so instead of finding a new panel to keep the search going.
