Functional Lab Testing in Tustin, 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.

Tustin has three different weeks. Old Town is walkable, with short blocks and a lot of sitting in cafes and small offices. Tustin Legacy, on the old base, is wide, new, and built around a car. North Tustin and the hills toward Foothill are grades, older homes, and a drive down to the 55. A low back from Legacy commuting is not a knee from a North Tustin hill. We ask which one you live in before we guess at a load.

The District and the shopping around the Legacy add standing errands on top of desk jobs. Neck pain and headaches often belong to the screen. Knee pain and hip pain show up when hill residents add steps without a plan. Plantar fasciitis shows up in people whose walking is almost all concrete between the car and a door.

The 55 south to the 73 is the usual path to La Alameda. About 16 miles. Twenty-five minutes is a good day. Forty is a 55 that is not cooperating. Address: 26400 La Alameda, Suite 100, Mission Viejo, CA 92691. Parking at the building. Monday through Thursday, 9 to 6.

Do not book the visit as a gap between school pickup in Old Town and a meeting. The exam needs you present, not halfway back on the freeway in your head. Call (949) 312-1754. A complimentary 20-minute consultation is available if you want to meet the doctors before an evaluation.

McKenzie Method work is a strong fit when back or neck pain has a direction that makes it better or worse. Corrective exercise is the homework. Adjustments are used when a specific joint is restricted, after the screen that says a thrust is appropriate.

Functional medicine visits cover thyroid, sleep, and gut health when those are the actual complaint. The Tustin chiropractor page collects the local routes into the three pillars.

Out of network. Superbill. HSA and FSA. No referral required. We will not change a prescription from your physician. Emergency symptoms, including sudden neurologic loss, go to the ER rather than to La Alameda.

Drs. Sani and Tara Kohen practice at FRI. Their backgrounds are on the about page. The suite and gym are on the office page.
