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 Calcium Micronutrient Test measures calcium levels in the blood to assess nutritional status and detect imbalances. Calcium is essential for strong bones and teeth, muscle contraction, nerve signaling, and heart function. This test helps identify deficiencies, excess, or issues with absorption and metabolism, supporting diagnosis and management of bone health, hormonal balance, and overall wellness.
Patient must be 18 years of age or older.
The Ionized Calcium Test measures the biologically active form of calcium in blood, essential for nerve signaling, muscle contraction, and heart function. Unlike total calcium tests, it reflects only free calcium not bound to proteins. Doctors order this test to evaluate parathyroid disorders, kidney disease, cancer, or critical illness. Results help diagnose hypocalcemia or hypercalcemia and guide treatment for electrolyte and metabolic imbalances.
The Calcium 24 Hour Urine Test measures calcium excreted over a full day to evaluate kidney function, bone health, and mineral balance. High levels may indicate hypercalciuria, kidney stones, hyperparathyroidism, or metabolic bone disease, while low levels can suggest malabsorption or dietary deficiency. This test helps clinicians assess calcium metabolism, monitor treatment, and investigate causes of abnormal mineral regulation.
The Calcium 24 Hour Urine with Creatinine Test evaluates calcium excretion alongside creatinine to provide insight into kidney health, mineral balance, and bone metabolism. Elevated or low calcium may reflect kidney stones, parathyroid disease, osteoporosis, or metabolic disorders. This test supports monitoring of calcium regulation, renal function, and systemic conditions linked to skeletal health.
The Calcium Total RBCs Test measures calcium levels within red blood cells, offering a more accurate reflection of long-term calcium status than serum testing. Calcium is essential for bone strength, nerve signaling, muscle contraction, and cellular function. Abnormal results may suggest deficiencies, imbalances, or metabolic conditions. This test supports evaluation of bone health, cardiovascular function, and nutritional status.
The Voltage-Gated Calcium Channel (VGCC) Antibody Test detects antibodies that target calcium channels in nerve endings, which can disrupt neurotransmission. These autoantibodies are associated with neurological and neuromuscular disorders such as Lambert-Eaton myasthenic syndrome (LEMS) and paraneoplastic syndromes. This test supports diagnosis, clinical classification, and monitoring of autoimmune channelopathies affecting nerve–muscle communication.
The PTH Intact Test measures intact parathyroid hormone (PTH) levels in blood to evaluate parathyroid gland function and calcium balance. Abnormal PTH may indicate hyperparathyroidism, hypoparathyroidism, kidney disease, or vitamin D imbalance. Doctors use this test to investigate osteoporosis, kidney stones, or unexplained calcium abnormalities. Results provide vital insight into endocrine function, bone metabolism, and overall calcium regulation.
