WebbTheir optimal buffering capacity, or range, is defined by the dissociation constant, or ka, of the acid. We commonly discuss buffering capacity in terms of the pKa or the logarithmic constant of ka. We consider the buffering capacity of a specific buffer to be the pKa ± 1. For example, a buffer with a pH of 6.8 has a pH buffering range of 5.8-7.8. Webb5 jan. 2024 · Parathyroid hormone (PTH) testing measures the level of this hormone in your blood. PTH is made by the parathyroid glands, which are four pea-sized glands located in the neck. PTH controls the level of calcium in your blood and bones.
