Part Descriptions
LP15257-6 Calcium
Calcium is the most plentiful mineral in the human body. Ninety-nine percent is stored in the bones and teeth where it provides structure and functionality. The remaining 1% of the body's calcium is necessary for vascular contraction and vasodilation, muscle function, nerve transmission, intracellular signaling, and hormonal secretion. Serum calcium levels do not fluctuate in response to dietary intake. Bone tissue is the reservoir for calcium and helps to maintain concentrations in the blood, the muscle, and intercellular fluids. As humans age, the bone is constantly being laid down and reabsorbed. In growing children, bone formation exceeds that of bone resorption. In young and middle-aged adults, the bone formation and resorption is about equal. In older adults, especially in post-menopausal women, bone loss exceeds that of bone formation, which is why their risk for osteoporosis continues to increase as they age.[https://ods.od.nih.gov/factsheets/Calcium-HealthProfessional/]

LP32035-5 Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
