Publikováno v: Journal of infection and chemotherapy : official journal of the Japan Society of Chemotherapy. 27(10)
Introduction In quantitative assays for hepatitis B virus (HBV) DNA, although the amplification reaction signal is detected for low-positive cases, quantification remains challenging. HBV reactivation has been reported in many studies, but only a few

[The Study of a New Formula for Correcting Serum Calcium Levels, Considering the Difference in Albumin Analysis Methods]
Autor: Makito, Tanaka, Yusuke, Takahashi, Yoshifumi, Umemori, Koichi, Asanuma, Satoshi, Takahashi
Publikováno v: Rinsho byori. The Japanese journal of clinical pathology. 64(6)
In Japan, Payne's formula [corrected Ca=total Ca+ (4-ALB)] has been used to correct serum calcium concentration levels. However, the current methods for measuring calcium and albumin differ from those that were used to establish the Payne's formula.
