Functional Lab Testing in Irvine, CA

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 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.

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.

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.

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.

Irvine's villages do not share a body. Woodbridge and University Park are older loops and pools. Turtle Rock and Quail Hill have more grade. The Spectrum and the Great Park are newer and more spread out. The job, for a lot of patients, is a campus along Jamboree, Barranca, or the Irvine Business Complex: long meetings, a badge, and a walk that is only from the garage. Neck, upper back, and headache complaints often start there. Knee and hip complaints often start on the village trails people use to undo the job.

We do not treat Irvine as a single activity level. A cyclist on the San Diego Creek trail and a software lead who has not exercised since a move from Woodbridge need different exams. Neck pain and headaches are common desk presentations. Hip and SI pain shows up when someone adds mileage fast. Say which village and which campus.

From central and north Irvine, I-5 south toward Mission Viejo is the simple drive. From the south villages and from many business parks, the 133 to the 73 toll road is often cleaner. About 12 miles. Twenty minutes is realistic off peak. Thirty-five is realistic when the 5 is slow through Lake Forest. The office is 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Building parking. Monday through Thursday, 9 to 6.

Irvine patients are used to efficient clinics. This one is deliberately less efficient. An exam takes time. If you need to be back on Jamboree for a meeting, book a morning visit and leave a buffer. Phone (949) 312-1754. The 20-minute consultation is the right first step if you are shopping for a style of care rather than ready for testing.

Corrective exercise and DNS are how we retrain sitting and breathing patterns after the exam shows they matter. Chiropractic adjustments are used when a joint is not moving, not as a subscription. Carpal tunnel symptoms get a neck screen and a nerve exam, because a keyboard is not automatically the wrist.

The same city asks functional medicine questions: thyroid, burnout-style fatigue people want explained, and gut symptoms after years of desk lunches. Those are history-first visits. The hub page is the Irvine chiropractor page.
