What serum CO2 actually measures, how to read low and high values, and which companion tests complete the acid-base picture.
Corrected calcium (albumin‑adjusted calcium) is a calculated estimate that modifies your routine blood calcium to account for albumin, the main protein that carries calcium in the bloodstream. In blood, calcium exists in two forms: attached to proteins, chiefly albumin (protein‑bound), and unbound (ionized). Available at 2,000+ lab locations and at-home (select states). See FAQs below
Carbon dioxide (CO2) blood testing reports the total CO2 in your blood, which mostly reflects bicarbonate, the body’s main base. In standard chemistry panels this “CO2” is predominantly bicarbonate (HCO3−), with small amounts of dissolved CO2 and carbonic acid (H2CO3). CO2 is made continuously as your cells burn carbohydrates and fats for energy. Available at 2,000+ lab locations and at-home (select states). See FAQs below
Hypercalcemia can signal parathyroid, bone, kidney, or malignancy-related disturbances in calcium regulation. Blood testing confirms and clarifies the physiology. At Superpower, we measure calcium, corrected calcium, and albumin for hypercalcemia. We offer in-clinic and at-home testing; home testing is currently available in selected states. (See FAQs below for more info).
Blood testing confirms dehydration by showing fluid balance and kidney stress. At Superpower, we measure sodium, the BUN/creatinine ratio, and albumin to quantify volume status. We offer in-clinic and at-home testing; home collection is currently available in selected states. (See FAQs below for more info).
