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 orders extensive functional medicine tests including hormone testing for women, thyroid panels, metabolic hormones like insulin and leptin, nutritional deficiency testing, inflammatory markers, autoimmune testing, pathogen and infection testing, cardiovascular risk factors, and other forms of comprehensive bloodwork depending on the patient’s individual needs.

Food Allergy & Sensitivity Testing

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

Functional Stool Testing

This state-of-the-art functional stool testing uses PCR DNA technology for advanced microbiome testing. We can now get a more accurate picture of the bacteria, both beneficial and pathogenic, yeast, viruses, and parasites that live in the digestive tract. This PCR stool testing also measures markers of inflammation, pancreatic enzymes, zonulin, which may indicate 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 and overall gut health.

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 hormone test offers one of the most extensive profiles of sex hormones, including estrogen, progesterone, and testosterone, along with adrenal hormones like cortisol and DHEA and their metabolites. This form of hormone balance testing is particularly important for estrogen metabolism, where some metabolites are protective while others may contribute to DNA damage and certain cancers.

Saliva Hormone testing

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

Functional nutrition testing

(urine, blood spot)
This is an advanced functional nutrition testing panel that measures a range of nutritional deficiencies, markers of oxidative stress, toxic elements and heavy metals, mitochondrial function markers, gut dysbiosis markers, amino acids, and offers the flexibility to add certain genetic SNP variants. This type of advanced functional lab testing helps support more personalized nutrition and wellness recommendations.

Heavy-metal Hair Analysis

The Metals Hair Test is a form of heavy metal hair analysis used to evaluate heavy metal testing concerns caused by pollution, environmental chemicals, and biomedical exposure such as contrast materials used for radiographic imaging. Biomarkers include a wide range of nutrient elements and toxic heavy metals.

DNA Diet Test

This DNA diet testing evaluates 20 different genes that help determine aspects of your metabolism. This type of genetic nutrition testing can help personalize your diet and lifestyle recommendations to support weight management and identify which dietary approach may work best for your unique genetic makeup, including low-carbohydrate, low-fat, or Mediterranean-style diets.

Neurotransmitter Test

This is a urine-based neurotransmitter testing panel that measures serotonin, dopamine, GABA, norepinephrine, epinephrine, glutamate, histamine, and PEA. Neurotransmitters play an important role in mood, cognitive function, energy, sleep, appetite, addiction behaviors, libido, and attention.

SIBO Breath Test

A SIBO breath test evaluates small intestinal bacterial overgrowth, a condition where bacteria migrate into the small intestine. Bacteria in this area ferment undigested food, potentially causing bloating, belching, nausea, reflux, and upper gastrointestinal discomfort. The test captures exhaled hydrogen (H2) and methane (CH4) gases to evaluate bacterial overgrowth and support more accurate digestive health testing.

Bone Resorption Test for osteoporosis (urine)

N telopeptide cross-links (NTX)
This bone resorption testing measures N-telopeptide cross-links (NTX) to assess bone resorption in patients with metabolic bone disease and to monitor therapy designed to slow or halt osteoporotic bone loss. This form of osteoporosis urine testing can help monitor bone health over time.

Mycotoxins (Mold toxicity) Test

This mycotoxin testing is a urine-based test for 31 of the most common toxins produced by molds. This form of mold toxicity testing is designed to identify very small mycotoxin molecules, making it more sensitive than many comparable tests.
