All Stress and Fatigue Tests

All Stress and Fatigue Tests brings together the labs most often used to investigate low energy, burnout, and stress-related symptoms. Because tiredness is multifactorial, we pair HPA-axis checks (cortisol patterns, DHEA-S) with common “look-alikes,” including thyroid imbalanceanemia/iron or B12 deficiencyblood sugar issuesinflammationelectrolyte or liver/kidney problems, and selected hormone markers.

A proactive plan often starts with 8–9 a.m. serum cortisol (± ACTH) ... See more

The Transferrin Test measures transferrin, a blood protein that transports iron, to evaluate iron status and nutritional health. High levels may suggest iron deficiency anemia, while low levels may indicate liver disease, malnutrition, or chronic illness. Doctors use this test alongside iron and TIBC to investigate fatigue, weakness, or anemia symptoms. Results provide vital insight into iron balance, red blood cell production, and overall metabolic function.

The Thyroid Stimulating Hormone (TSH) Test measures TSH levels in blood to assess thyroid function and diagnose hypothyroidism or hyperthyroidism. It evaluates how the thyroid controls metabolism, energy, weight, and heart rate. Doctors use the TSH test to investigate symptoms such as fatigue, hair loss, or mood changes. Frequently included in routine health exams, it is also key for monitoring thyroid disease treatment and overall endocrine balance.

The Urinalysis Complete Test evaluates urine for physical, chemical, and microscopic properties to assess kidney health, urinary tract infections, diabetes, and metabolic disorders. It measures appearance, concentration, pH, protein, glucose, ketones, blood, bilirubin, nitrites, leukocyte esterase, and microscopic cells or crystals. Doctors use this test in routine exams, to diagnose urinary symptoms, and to monitor chronic kidney or metabolic disease.

The Vitamin A Micronutrient Test measures blood levels of vitamin A (retinol) to assess nutritional status and detect deficiencies or excesses. Adequate vitamin A is essential for vision, immune defense, reproduction, and cellular health. This test helps evaluate malnutrition, absorption issues, or toxicity from supplements, supporting diagnosis and monitoring of overall health.

Patient must be 18 years of age or older.

The Vitamin B1 Blood Test measures thiamine levels to assess nutritional status and detect deficiency. Vitamin B1 is essential for energy metabolism, nerve function, and muscle health. Low levels may cause weakness, fatigue, irritability, or serious conditions such as beriberi or Wernicke-Korsakoff syndrome. Doctors order this test for patients with poor diet, alcoholism, or unexplained neurological symptoms. Results provide key insight into vitamin balance and metabolic health.

The Vitamin B12 and Folate Panel Test measures blood levels of vitamin B12 and folate to evaluate nutritional status, red blood cell production, and nervous system health. Deficiencies may cause anemia, fatigue, weakness, neuropathy, or cognitive decline, while elevated levels can indicate liver or kidney disease. Doctors use this panel to diagnose deficiency, monitor therapy, and assess absorption disorders such as pernicious anemia, Crohn’s disease, or celiac disease.

The Vitamin B2 Test measures riboflavin levels in the blood to assess nutritional status. Riboflavin is essential for energy metabolism, red blood cell production, and maintaining healthy skin, eyes, and nerves. Low levels may result from poor diet, malabsorption, or chronic illness, leading to fatigue, mouth sores, or anemia. Doctors use this test to detect deficiency, monitor supplementation, and support overall metabolic and nutritional health.

The Zinc Protoporphyrin (ZPP) Test measures ZPP levels in red blood cells to detect iron deficiency and lead exposure. When iron is low or lead interferes with hemoglobin production, ZPP accumulates, making it a sensitive early marker. Doctors use this test to screen for iron-deficiency anemia, monitor occupational lead exposure, and evaluate unexplained anemia, helping guide diagnosis, prevention, and treatment strategies.
