Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
The temperature at which a substance changes from one state or conformation of matter to another.
Studies to determine the advantages or disadvantages, practicability, or capability of accomplishing a projected plan, study, or project.
Any tests that demonstrate the relative efficacy of different chemotherapeutic agents against specific microorganisms (i.e., bacteria, fungi, viruses).

In analytical chemistry, the detection limit, lower limit of detection, or LOD (limit of detection), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%). The detection limit is estimated from the mean of the blank, the standard deviation of the blank and some confidence factor. Another consideration that affects the detection limit is the accuracy of the model used to predict concentration from the raw analytical signal. There are a number of different detection limits that are commonly used. These include the instrument detection limit (IDL), the method detection limit (MDL), the practical quantification limit (PQL), and the limit of quantification (LOQ). Even when the same terminology is used, there can be differences in the LOD according to nuances of what definition is used and what type of noise contributes to the measurement and calibration. The figure below illustrates the ...

In recent years, high levels of hormone residue in food, capable of damaging the health of consumers, have been recorded frequently. In this study, 195 raw milk samples were obtained from Tangshan City, China, and the concentrations of 22 steroid hormones were measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Cortisol was detected in 12.5% of raw milk samples (mean 0.61 µg/kg; range: <limit of quantification (LOQ)-0.94 µg/kg). Progesterone was detected in 85.9% of raw milk samples (mean 5.12 µg/kg; range: <LOQ-9.04 µg/kg). The concentration of cortisol present in milk was lower than the maximum residue limit defined in Japan (10 µg/kg). Children aged between one and five years were expected to be the at-risk population when exposed to detectable steroid hormone concentrations. Based on the mean and maximum concentrations of progesterone detected in milk, the contribution was 0.85% and 0.9%, and 1.48% and 1.6% of the acceptable daily intake for boys and

An accurate and sensitive reversed-phase high-performance liquid chromatograph-ic method for determination of sertraline in human serum is described using 4-chloro-7-nitrobenzofurazan as pre-column derivatization agent. The drug and an internal standard (azithrimycin) were extracted from serum using a mixture of diethyl ether-chloroform and subjected to the pre-column derivatization with the reagent. Analysis of the resulted derivatives was performed on a Lichrosorb CN (250×4.0 mm) column using a mobile phase composed of methanol and sodium phosphate buffer (0.05 M; pH 3.7) containing 2 ml/lit triethylamine (63:37 v/v). Detector response was monitored at excitation and emission wavelengths of 470 and 537 nm, respectively. The calibration curve was linear over the concentration range of 2 to 640 ng/ml. The lower limits of detection and quantification were 0.5 and 2 ng/ml, respectively. The validation of the analysis was carried out in terms of specificity, sensitivity, linearity, precision,

Results: The retention time was observed at 2.718 min. The system suitability results were found to be within limits. The method was precise, with lower than 2 %RSD and the calibration curve was linear (r2=1) over a concentration range of 2.5-160 µg/ml. The detection and quantification limit was found to be 0.045 µg/ml and 0.15 µg/ml, respectively. Recovery of the drug was found between 100.09-100.19%. The assay of ropinirole hydrochloride in ROPITOR® and ROPARK® tablets were found to be 100.4 and 103.60 %, respectively. The forced degradation studies were carried out to demonstrate the specificity of the method by exposing the API under conditions of hydrolysis, oxidation, thermal and photolytic as per ICH Q1A(R2) guidelines. ...
