All Hormone and Adrenal Tests

The Follicle-Stimulating Hormone (FSH) Test measures FSH levels to evaluate reproductive and endocrine health in both men and women. In women, it helps assess infertility, irregular periods, menopause, or ovarian function. In men, it is used to check sperm production and testicular function. Abnormal results may indicate PCOS, pituitary disorders, or hormonal imbalance. Doctors order this test to guide fertility treatment, hormone therapy, and overall reproductive care.

The FSH and LH Test measures follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to evaluate reproductive and endocrine health in both men and women. In women, it helps assess menstrual irregularities, infertility, menopause, or polycystic ovary syndrome (PCOS). In men, it aids in diagnosing low testosterone, infertility, or testicular dysfunction. Doctors also use this test to investigate puberty disorders, hormone imbalance, and pituitary function.

The GGT Test measures gamma-glutamyl transferase, an enzyme found in the liver and bile ducts, to evaluate liver health. Elevated GGT may indicate liver disease, bile duct obstruction, alcohol use, or medication side effects. Doctors order this test to investigate symptoms like fatigue, jaundice, dark urine, or abdominal pain and to monitor liver damage. It is often performed with other liver tests to provide a complete picture of liver and bile duct function.

The Gastrin Test measures gastrin hormone levels in blood, which regulate stomach acid production. Elevated levels may indicate Zollinger-Ellison syndrome, gastrinoma, pernicious anemia, or chronic atrophic gastritis. Doctors order this test for patients with recurrent ulcers, abdominal pain, or unexplained diarrhea. Results help evaluate abnormal acid production, detect tumors, and guide treatment for gastrointestinal and metabolic conditions.

The Glucose Test measures blood sugar levels to evaluate energy metabolism and screen for diabetes or prediabetes. Abnormal glucose may indicate hyperglycemia, hypoglycemia, or metabolic disorders. Doctors use this test during routine exams, to investigate symptoms like fatigue, excessive thirst, or frequent urination, and to monitor treatment for diabetes. It provides essential insight into how the body regulates blood sugar and overall metabolic health.

The Glucose Tolerance Test, 2 Specimens, 75g evaluates the body’s glucose metabolism by testing fasting and one-hour blood glucose levels after ingestion of a 75-gram glucose solution. It is an important diagnostic tool for identifying impaired glucose regulation, prediabetes, and type 2 diabetes. This test helps reveal early changes in insulin sensitivity and overall metabolic function.

The Gestational Glucose Tolerance Test, 3 Specimens, 75g evaluates glucose metabolism during pregnancy by testing fasting, 1-hour, and 2-hour blood glucose following a 75-gram glucose solution. It is widely used to diagnose gestational diabetes and assess maternal insulin function. Monitoring three intervals provides clinicians with essential information about pregnancy-related metabolic health and risk factors.

The Gestational Glucose Tolerance Test, 4 Specimens, 100g evaluates maternal blood sugar response at fasting, 1, 2, and 3 hours following a 100-gram glucose drink. It is widely used to detect gestational diabetes and impaired glucose regulation in pregnancy. By assessing four time points, the test delivers valuable data on insulin activity, maternal metabolism, and risks that may affect both mother and baby.

The Glucose-6-Phosphate Dehydrogenase (G6PD) Test measures enzyme activity to detect G6PD deficiency, a genetic condition that can lead to hemolytic anemia when exposed to certain foods, infections, or medications. Doctors order this test to assess unexplained anemia, jaundice, or family history of G6PD deficiency. Results help identify individuals at risk for red blood cell breakdown, guiding treatment, prevention, and safe medication use.

The Glucose Plasma Test measures the amount of glucose in the blood to assess how the body regulates sugar. Abnormal results may indicate diabetes, prediabetes, hypoglycemia, or other metabolic disorders. Doctors order this test for patients with symptoms like fatigue, excessive thirst, or frequent urination. It is also commonly used for routine health screening, monitoring diabetes treatment, and guiding lifestyle or medication adjustments.

The Glucose Random Test evaluates glucose levels in the blood without requiring fasting, making it useful for detecting abnormal sugar regulation. Elevated or low results may suggest diabetes, prediabetes, or hypoglycemia. This test supports assessment of metabolic function, carbohydrate processing, and systemic health, offering insight into symptoms like thirst, frequent urination, or unexplained fatigue.

The Glutamic Acid Decarboxylase-65 (GAD65) Antibody Test detects antibodies against the GAD65 enzyme, often linked to autoimmune type 1 diabetes and latent autoimmune diabetes in adults (LADA). Positive results indicate immune-related damage to insulin-producing beta cells. Doctors use this test to distinguish type 1 from type 2 diabetes, evaluate unexplained hyperglycemia, and assess risk in patients with suspected autoimmune endocrine disorders.

The Growth Hormone Test measures GH levels in blood to evaluate pituitary gland function, growth disorders, and metabolic health. Abnormal levels may indicate acromegaly, gigantism, or growth hormone deficiency. Doctors use this test to assess children with short stature, adults with suspected hormone imbalance, or patients with pituitary tumors. Results provide critical insight into endocrine function, metabolism, and overall growth regulation.

The Growth Hormone Test with 10 specimens measures hormone levels at ten collection times to evaluate pituitary gland function and hormone regulation. Monitoring growth hormone patterns throughout the day helps detect growth disorders, short stature, gigantism, acromegaly, and deficiency, while supporting assessment of metabolism, bone health, tissue repair, and overall endocrine system balance.

The Growth Hormone Test with 2 specimens measures growth hormone levels at two collection times to evaluate pituitary gland function and hormone regulation. Tracking these changes helps assess growth disorders, short stature, gigantism, or acromegaly, while providing insight into metabolic balance, bone development, and overall endocrine system health.

The Growth Hormone Test with 3 specimens measures hormone levels at three collection times to evaluate pituitary gland function and overall hormone regulation. Tracking growth hormone across intervals provides insight into growth disorders, short stature, gigantism, and acromegaly, while supporting assessment of metabolism, bone development, tissue repair, and endocrine health.

The Growth Hormone Test with 4 specimens measures hormone levels at four collection times to evaluate pituitary gland function and hormone regulation. Monitoring growth hormone changes helps detect growth disorders, short stature, gigantism, and acromegaly, while providing insight into metabolism, bone development, tissue repair, and overall endocrine health.

The Growth Hormone Test with 5 specimens measures hormone levels at five collection times to evaluate pituitary gland function and hormone regulation. Tracking growth hormone across the day provides insight into growth disorders, short stature, gigantism, acromegaly, and hormone deficiency, while supporting assessment of metabolism, tissue repair, bone health, and overall endocrine balance.

The Growth Hormone Test with 6 specimens measures hormone levels at six collection times to evaluate pituitary gland function and hormone regulation. Monitoring growth hormone patterns provides insight into growth disorders, short stature, gigantism, acromegaly, and deficiency, while supporting assessment of metabolism, tissue repair, bone development, and overall endocrine balance.
