High and low TSH levels are signals to interpret with Free T4 and the clinical setting. High TSH commonly accompanies insufficient thyroid hormone production; low TSH commonly accompanies thyroid-hormone excess. Pregnancy, pituitary disease, medicines, acute […]

Connect liver chemistry with glucose, lipids, blood counts, kidney findings, and clinical history to understand the whole pattern. Liver health lab tests become more useful when each result is connected to the question it can […]

Understand fatty liver terminology, the purpose of initial blood tests, and when imaging or further assessment may be needed. MASLD blood tests help evaluate liver injury, metabolic risk, and possible alternative causes, but they cannot […]

How AST, ALT, platelets, A1C, lipids, and secondary fibrosis tests work together to guide evaluation and follow-up. MASLD fibrosis risk can be present even when liver enzymes fall within the laboratory reference interval. Metabolic dysfunction-associated […]

How glucose, A1C, islet autoantibodies, C-peptide, and ketones help clarify diabetes type, remaining insulin production, and urgent risk. Adult-onset type 1 diabetes can initially resemble type 2 diabetes. In a slower-progressing presentation often called latent […]

Gout is an inflammatory arthritis caused by deposits of monosodium urate crystals in and around joints. Hyperuricemia means that serum urate—often reported as “uric acid”—is elevated. The two are related, but they are not interchangeable: […]

Clinical Summary Cushing syndrome cannot be confirmed or excluded by one random cortisol result. The workup begins by checking for glucocorticoid exposure. If endogenous cortisol excess remains a concern, a clinician usually selects one suitable […]

Cushing disease after pituitary surgery requires follow-up for both too little and too much cortisol. Early testing helps the surgical team assess remission and hormone safety. Later, testing evaluates recovery of normal cortisol production. After […]

Irregular periods and high testosterone can occur with PMOS, formerly called PCOS, but this combination does not establish the diagnosis by itself. Thyroid dysfunction, elevated prolactin, an adrenal enzyme disorder, medication exposure, and less common […]

How aldosterone, renin, the aldosterone-to-renin ratio, potassium, and kidney function help explain a hormonal cause of high blood pressure. Primary aldosteronism (PA) is a disorder in which one or both adrenal glands produce aldosterone partly […]

Glucose results tell you about blood sugar. Kidney, lipid, and liver results answer additional questions about your health. A person can have an improving A1C while urine albumin remains elevated, cholesterol-related risk persists, or liver […]

How calcium, PTH, vitamin D, kidney function, and urine calcium work together to clarify a possible parathyroid disorder. Primary hyperparathyroidism (PHPT) occurs when one or more parathyroid glands release hormone inappropriately for the calcium concentration […]

Editorial status: Draft for named medical and laboratory review. Product URLs are supported by current Ulta Lab Tests search and internal-link evidence but still require a final in-site canonical check before publication. Obesity is a […]

What is leptin, and should it be tested for weight loss? Leptin is a hormone made mainly by fat cells. It carries information about stored energy to the brain, especially the hypothalamus, and helps coordinate […]

Direct Answer Cortisol helps the body make fuel available during physical or psychological demands. Sustained pathologic cortisol excess, as occurs in Cushing syndrome, can raise glucose, impair insulin action, increase blood pressure, and alter body-fat […]

Direct Answer Progesterone is central to post-ovulation reproductive physiology, the menstrual cycle, the uterine lining, and pregnancy, but current evidence does not show that it independently causes sustained body-fat gain or produces weight loss. Natural […]

Direct answer: Most cisgender women and other people born without a typical prostate gland do not develop conventional prostate cancer. They do have Skene’s glands—small paraurethral glands that are developmentally related to prostate tissue—but benign […]

A blood-pressure cuff detects elevated pressure inside your arteries. Hypertension lab tests answer different questions: they can help show whether high blood pressure is affecting the kidneys, whether glucose or lipid abnormalities are adding cardiovascular […]

An insulin resistance diet is not one prescribed menu. It is a flexible eating pattern that emphasizes nonstarchy vegetables, fiber-rich carbohydrate foods, protein, and unsaturated fats while limiting sugary drinks, refined grains, and heavily processed […]

Diabetic ketoacidosis, or DKA, develops when insulin is too low for the body's needs and the liver rapidly produces acidic ketones. The resulting crisis is not defined by one abnormal value. Clinicians must establish three […]

Insulin resistance can develop quietly. Early in the process, the pancreas may release more insulin to keep glucose in the usual range. A normal fasting glucose therefore does not always mean the glucose-insulin system is […]

Originally published October 8, 2024. Updated August 26, 2026. Healthy sleep, regular physical activity, balanced meals, relaxation skills, and appropriate mental health support can reduce perceived stress and support normal hormone rhythms. However, cortisol is […]

Polyendocrine Metabolic Ovarian Syndrome (PMOS), formerly called Polycystic Ovary Syndrome (PCOS), is both a reproductive and metabolic condition. The diabetes connection is important because glucose dysregulation can develop even when fasting glucose, A1C, or body […]

Women’s hormone blood tests measure ovarian, pituitary, adrenal, thyroid, pregnancy, blood-count, and metabolic markers. Depending on the question, testing may include an estradiol measurement, progesterone measurement, FSH, LH, AMH, prolactin, or focused androgen, thyroid, pregnancy, […]

Neurological Blood Tests: The Direct Answer Neurological blood tests can help identify treatable or clinically relevant contributors to memory change, numbness, weakness, headache, balance problems, and other neurological symptoms. Common questions involve blood-cell patterns, glucose […]
