NationWide Specialist Laboratories – Parathyroid Hormone
Parathyroid hormone (PTH) and ionised calcium (iCa) measurements are the mainstay of calcium investigations and their combined measurement should be considered in both hypo- and hypercalcaemic situations where the cause is not immediately obvious.

Elevated FGF23 Levels Are Associated with Impaired Calcium
Main Outcome Measures: Ionized calcium (iCa), PTH, and FGF23 levels were measured during HD. The slope of the relationship between iCa and PTH (a marker of parathyroid gland mass) and the iCa level required for a 50% reduction in PTH were determined, and the association of these with FGF23 levels was determined.Cited by: 18Publish Year: 2010Author: James B.

pH-adjusted ionized calcium - acute care testing
pH-adjusted ionized calcium by Christopher R. McCudden Thus, iCa 2+ is the preferred test in patients with acid-base disorders, those receiving blood transfusions containing citrate anticoagulant, those with late-stage renal disease, and hospitalized or critically ill patients.
The Vitamin D, Ionised Calcium and Parathyroid Hormone
Bioactive vitamin D and PTH will synergistically increase plasma iCa via enhancing intestinal absorption of dietary calcium, increasing osteoclast activity to liberate calcium and reducing renal calcium excretion. The provision of supplemental vitamin D progressively increases iCa and concomitantly suppress PTH Cited by: 7Publish Year: 2015Author: Virginie Lam, Ryusuke Takechi, Menuka Pallabage-Gamarallage, Corey Giles, John C.

PTH-calcium curve and the set point of calcium in primary
The set point of calcium (calculated as midpoint between maximal and minimal PTH secretion), the serum ICa at maximal PTH secretion and, the serum ICa at maximal PTH inhibition is reported for each individual patient affected by normocalcaemic (n=16, triangles) and hypercalcemic secondary HPT (n=19, asterisks) and, for 14 normal subjects (squares).Cited by: 79Publish Year: 1999Author: Fabio Malberti, Marco Farina, Enrico Imbasciati
Intact parathyroid hormone, ionized calcium and calcium
All showed suppression in the elevated plasma intact PTH concentration and in 6 the intact PTH value normalized. The PTH-MM value did not normalize in any of the patients. During oral calcium treatment the degree of intact PTH suppression at an achieved concentration of plasma iCa Cited by: 9Publish Year: 1987Author: Kari Pietilä, Pertti Mörsky, Amos Pasternack, Jukka Mustonen, Timo Koivula

Calcium, parathyroid hormone, oxytocin and pH profiles in
The objectives were to i) determine serum concentrations of total calcium, ionized calcium (iCa), parathyroid hormone (PTH), and blood pH in normally whelping bitches throughout the peri-parturient period; and ii) investigate relationships among iCa, PTH, and acid-base status, and the role that they and oxytocin may have in the underlyingCited by: 10Publish Year: 2010Author: F.K.

(ICa) (PTH) results in horses - Tufts University
PDF fileIn 33 sera with normal ICa, the median PTH was 4.7 (0.8‐47) pM. In 11 samples with elevated ICa, the median PTH was 10.3 (0.2‐ 42.4) pM. The higher median PTH values in samples with low or elevated ICa are indicative of horses with secondary and primary hyperparathyroidism, respectively.
