The Calcium Test measures calcium levels in blood to assess bone health, parathyroid function, and metabolic balance. Abnormal levels may indicate bone disease, parathyroid disorders, kidney disease, or certain cancers. Both low and high calcium can cause muscle spasms, weakness, or irregular heartbeat. Doctors order this test to monitor osteoporosis, kidney stones, or endocrine disorders. Results provide essential insight into bone, nerve, and overall metabolic health.

The Heavy Metals Micronutrients Blood Test Panel measures levels of arsenic, cadmium, cobalt, lead, and mercury to assess exposure and potential toxicity. These metals, found in the environment, food, or workplaces, can affect the nervous system, kidneys, bones, and overall health. This panel helps detect harmful accumulation, guide treatment, and monitor risks from environmental or occupational exposure.

Patient must be 18 years of age or older.

The Candida Albicans (M5) IgE Test measures IgE antibody response to Candida albicans, a common yeast that can trigger allergic reactions. Elevated IgE may indicate sensitivity linked to respiratory, skin, or digestive symptoms. Physicians use this test to identify potential allergic responses, distinguish yeast-related immune activity, and guide evaluation of conditions affecting allergy, inflammation, or overall immune health.

The Candida Albicans IgG, IgA, IgM Antibodies Test detects immune response to Candida albicans, a yeast that can cause fungal infections. Measuring all three antibodies helps identify recent, chronic, or past exposure. Doctors order this test for patients with recurrent yeast infections, digestive issues, fatigue, or weakened immunity. Results provide valuable insight into fungal overgrowth, guiding diagnosis, treatment, and monitoring of candidiasis or systemic infection.

The Cortisol Saliva 4 Samples Test measures cortisol levels at four points during the day to assess adrenal gland function and circadian rhythm. Abnormal patterns may indicate adrenal insufficiency, Addison’s disease, Cushing’s syndrome, or chronic stress. Because saliva reflects active hormone levels, this noninvasive test is ideal for evaluating diurnal cortisol changes, supporting diagnosis, and guiding treatment for endocrine and stress-related disorders.

The Cortisol Test with 2 specimens measures adrenal gland function by evaluating cortisol levels at two collection times. Tracking changes in this stress hormone helps assess adrenal performance, circadian rhythm, and the body’s stress response, while offering insight into conditions such as adrenal insufficiency, Cushing’s syndrome, Addison’s disease, and overall endocrine balance.

The Cortisol Test with 3 specimens measures adrenal gland function by evaluating cortisol levels at three collection times. Monitoring this stress hormone helps assess circadian rhythm, adrenal performance, and daily hormone balance, while providing insight into adrenal insufficiency, Addison’s disease, Cushing’s syndrome, and overall endocrine and metabolic health.

The Cortisol AM Test measures morning cortisol levels in blood to evaluate adrenal gland function and stress response. Cortisol peaks in the morning, making this test critical for detecting adrenal insufficiency (Addison’s disease), Cushing’s syndrome, or other hormone imbalances. Doctors also use it to investigate fatigue, weight changes, or high blood pressure. This test provides important insight into endocrine health, metabolism, and long-term stress regulation.

The Cortisol Free 24-Hour Urine with Creatinine Test measures cortisol excreted in urine over 24 hours, with creatinine used to validate collection. Elevated cortisol may indicate Cushing’s syndrome, while low levels can suggest Addison’s disease or adrenal insufficiency. Doctors order this test for patients with obesity, fatigue, high blood pressure, or abnormal hormone symptoms. Results provide critical insight into adrenal gland function and hormone regulation.

The Cortisol PM Test measures afternoon cortisol levels to evaluate adrenal and pituitary function. Cortisol normally drops later in the day, so abnormal results may indicate Cushing’s syndrome, adrenal insufficiency (Addison’s disease), or hormone imbalance. Doctors order this test to investigate fatigue, obesity, high blood pressure, or irregular sleep patterns and to monitor adrenal disorders.
