Diagnostic Testing

Comprehensive bloodwork

The benefit of testing through bloodwork is that several areas can be assessed at the same time (and insurance will often cover it). Dr. Goldberg routinely orders tests like the CBC, metabolic panel, and lipid panel but also will order extensive hormone testing, thyroid panels, metabolic hormones like insulin and leptin, nutritional deficiency testing, inflammatory markers, autoimmune markers, pathogen/infection testing, cardiovascular risk factors, and other tests depending on the patient’s individual needs.

Food Allergy & Sensitivity Testing

Assessing food reactions can be challenging because there are so many different types of reactions each individual can
experience. After 20 years of using different types of tests, the one I feel is the most accurate is the P88 Dietary Antigen test. It measures four distinct immune/inflammatory reactions (true allergies, delayed sensitivities, and inflammatory reactions). These reactions can cause fatigue, headaches, inflammation, weight gain, joint pain, digestive issues, skin reactions, and can contribute to autoimmune disease and histamine issues, etc. available as a blood draw or fingerstick.

Functional Stool Testing

This state of the art test uses PCR DNA technology to evaluate the microbiome. We can now finally get an accurate picture of the bacteria (beneficial and pathogenic), yeast, viruses, and parasites that live in the digestive tract. This test also measures markers of inflammation, pancreatic enzymes, zonulin (a sign of leaky gut), immune function in the digestive tract, and detoxification. It is a great way to determine what is working and what is not working in your digestion.

Dutch Dried Urine Hormone testing

Hormone testing can be done through blood, saliva, or urine. When a very comprehensive picture of hormone balance is required, the DUTCH test offers the most extensive profile of sex (Estrogens, progesterone, testosterone) and adrenal hormones (Cortisol, DHEA) along with their metabolites. This is particularly important for estrogen where some metabolites are protective while other metabolites can cause DNA damage and contribute to certain cancers.

Saliva Hormone testing

Assessing hormones through saliva has several advantages over bloodwork. Saliva collection is typically done at home which allows several collection readings throughout the day. This is particularly helpful for cortisol which changes significantly with circadian rhythm. It also accurately measures “active” hormone levels as opposed to total levels.

Functional nutrition testing

(urine, blood spot)
This is an advanced comprehensive functional nutrition test. It measures a range of nutritional deficiencies, markers of oxidative stress, toxic elements and heavy metals, mitochondrial function markers, gut dysbiosis markers, amino acids, and even offers the flexibility to add on certain genetic SNP variants.

Heavy-metal Hair Analysis

The Metals Hair Test analyzes heavy metal toxicity caused by pollution, environmental chemicals, and even biomedical exposure like contrast materials used for radiographic imaging. Biomarkers include a wide range of nutrient elements and toxic heavy metals.

DNA Diet Test

This is a genetic test that analyzes 20 different individual genes that help determine aspects of your metabolism. This can help personalize your diet and lifestyle recommendations to manage weight and provides insight into which diet type might be most suitable for you according to your genetic make up (low carbohydrate, low fat, Mediterranean diet, etc.).

Neurotransmitter Test

This is a urine test that measures serotonin, dopamine, GABA, norepinephrine, epinephrine, glutamate, histamine, and PEA. Neurotransmitters are important for mood, cognitive function, energy, sleep, appetite, addiction behaviors, libido and attention.

SIBO Breath Test

Small intestinal bacterial overgrowth is a condition where bacteria migrates up to the small intestine. Bacteria in this area ferments undigested food, potentially causing bloating, belching, nausea, reflux, and pain in the upper part of the gastrointestinal tract. The breath test captures exhaled hydrogen (H2) and methane (CH4) gases to evaluate bacterial overgrowth of the small intestine.

Bone Resorption Test for osteoporosis (urine)

N telopeptide cross-links (NTX)
This test is used to assess bone resorption in patients with metabolic bone disease and to monitor therapy to slow or halt osteoporotic bone loss.

Mycotoxins (Mold toxicity) Test

This test is a urine-based test for 31 of the most common toxins produced by molds. This test is able to identify mycotoxins, small molecules, as small as five PCG which makes it much more sensitive than comparable tests.
