We tested isolates of pneumococcus for sensitivity to oxacillin, penicillin, erythromycin, sulphamethoxazole, tetracycline, and chloramphenicol using a disc diffusion method (calibrated dichotomous susceptibility, CDS) [ 11].
Serum creatinine will be measured by automatic analyser (using the Jaffe method calibrated to IDMS values).
Serum creatinine was analyzed using the enzymatic method, calibrated to be traceable to isotope dilution mass spectrometry.
Creatinine was assayed using a kinetic alkaline picrate method, calibrated using material traceable to National Institute of Standards and Technology NIST Standard Reference Materialal 914a, with a mean expanded uncertainty of 13.4% (7.3% excluding biological variation).
Hence, we have used a simple method to calibrate the camera that only requires the selection of four points on the image that forms a rectangle on the road plane, and two metric references.
A Saltzman colorimetric method using a spectrometer calibrated at 540 nm was employed to analyze the mass of NO2 on the collection filter that was then subjected to a mass transfer equation to calculate the level of NO2 for the 24 hours of sampling duration.
We estimated divergence times using the Bayesian relaxed clock method calibrated with node ages from previous studies.
A research project is conducted to study hygrothermal performance of PAC block walls using a calibrated hot box method.
Blood pressure was measured in a sitting position, 2 times in each upper arm using the Korotkoff-Riva-Rocci method, using a cuff, a calibrated manometer and a stethoscope.
In case the study cannot be rescheduled or when elevated glucose levels cannot be ruled out, blood glucose levels must always be measured using a calibrated and validated method and SUV must be reported with and without glucose correction.
