Functional Medical Tests in Singapore

Provided by the Mosaic Diagnostics (formally Great Plains Laboratory) in Canada

We have recently expanded our testing range to include 5 new functional medical tests, along with a series of videos that provide more information about these tests. Unlike conventional medical tests available from your doctor, functional medical tests are exclusively offered by practitioners specialising in identifying the root causes of pain, problems or diseases.


These tests are crucial for investigating underlying issues, allowing us to pinpoint the primary concern and develop the most effective, lasting solutions.

This convenient functional medical testing cheat sheet matches common conditions with the corresponding test that helps uncover their root causes. Functional medical tests are at the forefront of health technology. They are evidence-based and rooted in the latest science, but they haven’t been around long enough to be included in medical text books or to be paired with pharmaceutical solutions. Instead, they focus on helping find lifestyle interventions that offer true long-term benefits.


There are many more conditions that these tests can help address, so please don't hesitate to contact us if you have specific questions or concerns.

Organic Acids Test (OAT)

A Nutritional and Metabolic Snapshot


Organic acids are products of the body’s metabolic pathways. Evaluation of these downstream metabolites from various metabolic pathways provides insight into important areas related to gut health, mitochondrial dysfunction, neurotransmitter status, indicators of detoxification and macronutrient breakdown and nutritional status. This makes organic acid testing a valuable tool to assess the functional need for essential nutrients, diet modification, antioxidant protection, detoxification, and other therapies.


The Organic Acids Test (OAT) provides a comprehensive nutritional and metabolic snapshot of an individual’s overall health. The OAT measures 76 organic acids from one easy to collect urine sample.

Comprehensive Stool Analysis

The Key to Optimal Health


Imbalances in gastrointestinal function can lead to both local and systemic health issues, with the gut microbiome playing a vital role in supporting overall health. Our Comprehensive Stool Analysis profile helps identify the underlying causes of acute and chronic symptoms, enabling providers to create personalized treatment plans.


The Comprehensive Stool Analysis measures key markers of digestion, absorption, and intestinal function, including a comprehensive bacteriology and yeast culture to detect beneficial, imbalanced, and dysbiotic flora. We use gold standard methods, such as PCR, to identify infectious pathogens and parasites, and perform antimicrobial susceptibility testing on cultured bacterial and fungal species to recommend prescriptive and natural agents.

Saliva Hormones Profile

Addressing Hormonal Imbalances


Hormones play a vital role in maintaining physical and mental health as imbalances can lead to serious health problems. Both men and women produce hormones like estrogen and testosterone, and balance is key for optimal health.


The old “one-size-fits-all” approach to hormone replacement therapy is outdated, MosaicDX offers comprehensive salivary hormone profiles that measure both sex and stress hormones. Salivary measurement of hormones is non-invasive and convenient to asses unbound biologically active hormone levels. Our profiles help identify hormonal imbalances, allowing for personalized hormone replacement therapies and nutritional interventions.

Explaining Cortisol Imbalance

Metals – Toxic + Nutrient Elements

Essential Nutrient and Toxic Elements Testing


Heavy metals can accumulate in the body and disrupt the balance of essential nutrients, and become toxic to organ systems. While certain elements are vital for proper body function, others such as mercury, lead, cadmium, aluminum, and arsenic are toxic to the human body and interfere with its functioning. These toxic metals have no known physiological functions and can cause harm to organ systems.


MosaicDX offers various testing options, including urine, blood, stool, and hair samples, to evaluate the status of toxic metals and essential elements. This allows practitioners to select the most clinically appropriate option for their patients.

IgG Food MAP with Candida + Yeast

Uncovering Food Sensitivities


IgG food sensitivities provide a useful guide for personalized rotation/elimination diets with clinical impact associated with a variety of diseases. People may continue to eat offending foods unaware of their potential adverse effects, because symptoms associated with food sensitivities may occur hours or days after the offending food was eaten.


MosaicDX’s IgG Food MAP test is a comprehensive food sensitivity test that measures antibodies to 190 common foods, herbs, and spices typically found in Western, Asian, and Mediterranean diets also includes results for candida and yeast. This test is available in both serum and dried blood spot formats, making it easy and convenient for patients. By identifying food sensitivities, this test can help individuals customize their diet leading to improvements in overall health and wellbeing.
