How does this work?

1) Set the Appointment

You take the first step by setting an appointment for a free 20 minute consultation in Dr. Rosenberg’s calendar.

2) The Meeting

Before the meeting it is helpful to email a brief medical history to

We meet by Google Meet, Zoom, or phone for 20 minutes to discuss the details.

3) Agreement and Plan

If both parties agree to work together Dr. Rosenberg then puts together a personalized plan with full information about the test with pricing and emails it to you.

4) Payment 

Payment for testing and services is rendered to PayPal or direct transfer to a bank account.

5) The Test

The test is ordered and arrives at your home by courier.
You take the test according to instructions and send it back to the lab in a prepaid pre-addressed courier envelope.

6) The Results

Results arrive in about 2 weeks.  At this time another meeting will take place to discuss the results and a game plan.

If needed professional grade supplements will be prescribed.

There is an option for ongoing monthly coaching.

What We Do

Functional Lab Tests

OAT Test

The Organic Acids Test offers a comprehensive metabolic snapshot of a patient’s overall health with 76 markers.  It provides an accurate evaluation of intestinal yeast and bacteria.  Abnormally high levels of these microorganisms can cause or worsen behavior disorders, hyperactivity, movement disorders, fatigue and immune function. Many people with chronic illnesses and neurological disorders often excrete several abnormal organic acids in their urine. The cause of these high levels could include oral antibiotic use, high sugar diets, immune deficiencies, acquired infections, as well as genetic factors.

Abnormalities detected using the OAT can be treated using supplements, such as vitamins and antioxidants, or dietary modification. Patients who have been diagnosed using this test and adjusted their diets accordingly have reported significant improvement in their conditions including decreased fatigue, regular bowel function, increased energy, alertness and concentration, improved verbal skills, less hyperactivity and decreased abdominal pain.

Dried Urine Test for Comprehensive Hormones


Over time, men experience a gradual loss of hormones produced in the gonads and adrenal glands. Testosterone and DHEA levels fall and estrogen levels tend to rise. Male menopause, or what doctors call ‘andropause,’ can create symptoms of weight gain, lower sex drive, depression, hair loss, sleeping troubles, fatigue, and increased prostate cancer risk. Many men feel this is part of getting older and do not know there is treatment to help them maintain a healthy lifestyle.


Millions of women suffer from hormonal imbalances. Whether it is menopause, weight gain, fatigue, low libido, premenstrual symptoms (PMS), mood swings, or depression, these symptoms can lead to more serious problems if misdiagnosed. Identifying the root cause of chronic health issues is certainly correctable, but only if properly identified.

The DUTCH Test® was created to provide insight into many of these concerns, working to deliver the most complete assessment of sex and adrenal hormones, along with their metabolites, in one easy to administer test. No blood to draw, spitting in tubes, or filling up jugs of urine. Our dried urine collection process is great for baseline measurements of women with hormonal imbalances and for Hormone Replacement Therapy (HRT) monitoring.

After utilizing the DUTCH Test®, you will be able to work with your medical provider to continue to track and evaluate hormone levels, ensuring they are at their optimum balance.

This advanced hormone testing was developed to improve on available hormone testing options. DUTCH offers the most extensive profile of sex and adrenal hormones along with their metabolites. Additionally, the daily (diurnal) pattern of free cortisol is included, along with melatonin (6-OHMS), 8-OHdG, and six organic acids. This unique combination of clinical information is not available by any other method.

Toxic Chemicals Profiles

These are three separate tests that screen for the presence of various toxic chemicals, including mercury (Mercury Tri-Test), other toxic metals, and non-metal toxic chemicals such as organophosphate pesticides, phthalates, benzene, and more. We are exposed to these chemicals through the products we consume and environmental pollution, and they can have a detrimental effect on our health.

With this information, a patient can pinpoint the source and scope of exposure and eliminate it.

Salivary Cortisol Testing

This test evaluates five conveniently collected saliva samples to assess levels of cortisol, insulin, DHA/DHEA-S, secretory IgA, 17-OH progesterone, and wheat gluten sIgA. Because the saliva is collected over a period of 24 hours, the test provides more complete information about the body’s stress response than a single test would—such as the standard serum or urine testing a conventional doctor may offer. Abnormal results are related to chronic stress and stress-related symptoms such as insomnia, anxiety and fatigue.

PCR Genetic Stool Testing

This test utilizes cutting-edge DNA analysis technology to detect microorganisms that are generally undetectable when tested via conventional culture techniques. Because most of the bacteria of the GI tract are anaerobic (meaning, they don’t live or grow when oxygen is present), culture-based methods cannot cultivate them, leaving up to 50% of bacterial species virtually invisible. The GI-MAP (GI Microbial Assay Plus) stool test utilizes PCR technology to provide a DNA/PCR-based stool test that can detect bacteria, parasites and viruses that may be undetected by standard culture testing. It can evaluate the presence of opportunistic organisms, normal flora, fungi, parasites and antibiotic resistance genes. Additionally, it tests for immunologic markers for GI health and function, including SIgA, Elastase, Calprotectic and Anti-gliadin testing.

As with the OAT test, discovering the presence of previously undetected bacteria can provide a new approach for treating a variety of conditions.

Male and Female Hormone Panel

The Male Hormone Panel tests for seven different hormone levels to provide a comprehensive picture of male hormonal balance. The expanded panel also adds a measurement for follicle stimulating hormone (FSH) and luteinizing hormone (LH), providing addition information. This data can be helpful when assessing conditions relating to infertility, sexual dysfunction, and andropause (an age-related decline in male hormone levels).

The cycling Female Hormone Panel (FHP) measures 11 saliva samples that are gathered at specific time points throughout one complete menstrual cycle. It provides a dynamic mapping of the active levels of estradiol (E2) and progesterone (P) as well as the cycle average of testosterone and DHEA. The expanded panel also includes FSH and LH, which can help draw a more complete picture of what may be causing any symptoms related to the female reproductive system (menstrual problems, menopause, infertility, etc.).

These are a few of the tests that can help you figure out what is causing your health problem
