The immunosuppressants cyclosporine, tacrolimus, sirolimus, everolimus, and probably also mycophenolic acid require therapeutic drug monitoring (TDM)-guided dosing to ensure that blood concentrations are kept within the target range in transplant patients. Reliable, accurate, and precise test methods are therefore essential to effectively monitor levels and to make proper dose adjustments. Data...

The triangle odor bag method, the most popular olfactory sensory test in Japan, was first developed in 1972, and introduced into the Offensive Odor Control Law in 1995. This is an air dilution method in which “odor index” is measured. In recent years, the necessity of developing quality control system for olfactometry and standardization of measurement procedure for the promotion of nationwide ...

The increase of proinflammatory cytokines in vaginal secretions may serve as a surrogate marker of unwanted inflammatory reaction to microbicide products topically applied for the prevention of sexually transmitted diseases, including HIV-1. Interleukin (IL)-1beta and IL-6 have been proposed as indicators of inflammation and increased risk of HIV-1 transmission; however, the lack of information...

Abstract We used absolute primary acoustic gas thermometry (AGT) to calibrate a Pt–Co resistance thermometer on the thermodynamic temperature scale by measuring speed of sound in helium at T * chosen be near triple point neon, Ne . Prior present AGT, was with neon triple-point cell as part an interlaboratory comparison. Taken together, results comparison and AGT redetermined = (24.555 15 ± 0.00...

BACKGROUND In an effort to improve interlaboratory agreement in the monitoring of unfractionated heparin (UFH), the College of American Pathologists (CAP) recommends that the therapeutic range of the activated partial thromboplastin time (APTT) be defined in each laboratory through correlation with a direct measure of heparin activity such as the factor Xa inhibition assay. Whether and to what ...

International guidelines define a BK virus (BKV) load of ≥4 log10 copies/ml as presumptive of BKV-associated nephropathy (BKVN) and a cutoff for therapeutic intervention. To investigate whether BKV DNA loads (BKVL) are comparable between laboratories, 2 panels of 15 and 8 clinical specimens (urine, whole blood, and plasma) harboring different BKV genotypes were distributed to 20 and 27 French h...

The male and female pubertal assays, which are included in the U.S. Environmental Protection Agency's (EPA) Endocrine Disruptor Screening Program (EDSP) Tier 1 battery, can detect endocrine-active compounds operating by various modes of action. This article uses the collective experience of three laboratories to provide information on pubertal assay conduct, interlaboratory reproducibility, end...

Abstrac t An interlaboratory comparison of microwave power measurement (project UME-EM-10-02) was carried out among eight (8) laboratories in Turkey. In this comparison, it was requested to make microwave power measurements at +10 dBm, 0 dBm and -15 dBm power levels with 0.03 GHz, 1 GHz, 7 GHz, 12 GHz and 18 GHz frequencies with their own measurement systems and methods. The measurement results...
