We provide a full range of biochemical laboratory tests for diagnosing and managing endocrine disorders. These include routine hormone immunoassays, autoantibody panels, genetic testing (in advanced setups), and dynamic stimulation/suppression tests.

1.  Diabetes Mellitus and Glucose Homeostasis Tests

These are core for diagnosing and monitoring type 1, type 2, gestational diabetes, prediabetes, insulin resistance, and hypoglycemia.

• Fasting Plasma Glucose (FPG)
• Random Plasma Glucose
• 2-hour Oral Glucose Tolerance Test (OGTT) — often with insulin measurements
• Hemoglobin A1c (HbA1c)
• Fructosamine (alternative for HbA1c interference)
• Insulin levels (fasting or during OGTT)
• C-peptide (fasting, postprandial, or stimulated)
• Proinsulin (in select hypoglycemia cases)
• Autoantibodies for type 1 diabetes/autoimmune diabetes: Glutamic acid decarboxylase (GAD-65), Islet antigen-2 (IA-2), Zinc transporter-8 (ZnT8), Insulin autoantibodies (IAA)
• Ketone testing (blood beta-hydroxybutyrate or urine acetoacetate)
• Continuous glucose monitoring interpretation support

2. Thyroid Gland Tests

For hypo/hyperthyroidism, thyroiditis, nodules, Graves’ disease, and thyroid cancer monitoring.

• Thyroid-Stimulating Hormone (TSH)
• Free Thyroxine (Free T4)
• Free Triiodothyronine (Free T3)
• Total T4 and Total T3 
• Thyroid antibodies: Anti-Thyroid Peroxidase (TPOAb), Anti-Thyroglobulin (TgAb), TSH Receptor Antibodies (TRAb/TSI for Graves’)
• Thyroglobulin (Tg) — for cancer follow-up
• Calcitonin — for medullary thyroid carcinoma screening/monitoring
• Thyroglobulin antibodies (with Tg for interference check)
• USG guided FNAC/biopsy of thyroid nodule

3. Adrenal Gland Tests

For Cushing’s syndrome, Addison’s disease, primary aldosteronism, congenital adrenal hyperplasia, pheochromocytoma/paraganglioma.

• Morning serum Cortisol (or random)
• Adrenocorticotropic Hormone (ACTH)
• 24-hour Urinary Free Cortisol
• Dexamethasone Suppression Test (low-dose, high-dose, or overnight)
• ACTH (Cosyntropin/Synacthen) Stimulation Test
• Aldosterone (plasma or urine) and Plasma Renin Activity (or Direct Renin) — Aldosterone/Renin Ratio
• Dehydroepiandrosterone sulfate (DHEA-S)
• 17-Hydroxyprogesterone (basal or ACTH-stimulated for CAH)
• Androstenedione
• 21-Hydroxylase Antibodies (21OH-Abs)
• Plasma or urinary fractionated Metanephrines/Catecholamines (for pheochromocytoma)

4. Pituitary Gland Tests

For pituitary adenomas, hypopituitarism, acromegaly, prolactinoma, etc.

• Prolactin
• Growth Hormone (GH) — basal or stimulated/suppressed
• Insulin-like Growth Factor-1 (IGF-1)
• Follicle-Stimulating Hormone (FSH)
• Luteinizing Hormone (LH)
• ACTH 
• TSH and Free T4 

• 5. Parathyroid and Bone/Calcium Metabolism Tests

For hyper/hypoparathyroidism, vitamin D disorders, and related bone health.

• Parathyroid Hormone (PTH, intact or 1-84)
• Serum Calcium (total and ionized)
• Phosphate
• 25-Hydroxy Vitamin D
• 1,25-Dihydroxy Vitamin D 
• 24-hour Urinary Calcium and Creatinine

• 6. Gonadal (Reproductive) Hormone Tests

For hypogonadism, PCOS, infertility, disorders of sexual development, menopause/andropause.

• Testosterone (total, free, bioavailable) + Sex Hormone-Binding Globulin (SHBG)
• Estradiol (E2)
• Progesterone
• LH/ FSH
• Anti-Müllerian Hormone (AMH)
• Inhibin B 
• Human Chorionic Gonadotropin (hCG)
• DHEA-S and Androstenedione 
• Karyotyping

7. Other Specialized/Miscellaneous Endocrine Tests

• For multiple endocrine neoplasia (MEN), carcinoid, etc.: Chromogranin A, Gastrin, VIP, etc.
• Electrolytes, osmolality, urine sodium (for SIADH, diabetes insipidus)
• Genetic testing panels for hereditary endocrine disorders (e.g., MEN1/2, CAH genes, MODY diabetes genes)
• Urine steroid profiling or salivary hormone panels (cortisol, etc.)

8. Dynamic Function (Provocation/Suppression) Tests

• ACTH (Cosyntropin) Stimulation Test (adrenal insufficiency)
• Dexamethasone Suppression Tests (Cushing’s)
• Oral Glucose Tolerance Test with GH suppression (acromegaly)
• GnRH Stimulation Test (gonadotropin reserve)
• Water Deprivation Test ± Desmopressin (diabetes insipidus)
• 72-hour Supervised Fast or Mixed Meal Test (hypoglycemia/insulinoma)
