Laboratory Tests to Ascertain Tumor Resistance to Drugs Are Available

Laboratory tests of antifungal drugs.

The procedures evolved in the author's laboratory over the past 20 years for the microbiological assessment of antifungal drugs are described; methods are detailed for the estimation of the sensitivity of pathogenic fungi to therapeutic agents and for the assay of those agents in body fluids. The preparation and maintenance of stock reference solutions of the drugs, the culture media used, and ...

Are Guidelines Guiding us on How to Utilize Laboratory Tests?

Increasing patient risks and costs associated with the delivery of health care services have been related to inappropriate and uncontrolled use of biomarkers which make evidence-based guideline recommendations for best practice increasingly important. The translation of basic scientific discoveries into clinically meaningful studies and then to evidence-based clinical practice guidelines (CPGs)...

liver fibrosis in patients with chronic liver diseases: are laboratory tests useful to diagnosis?

Interference in laboratory tests

Interference in clinical laboratory testing can create discrepancies in test results which can lead to patient harm.  In clinical chemistry, interference is defined as a cause of medically significant difference in the measurand test result due to another component or property of the sample. Interference by endogenous and exogenous substances with assays for clinical analytes is a common prob...

Laboratory Model Tests to Study the Behavior of Soil Wall Reinforced by Weak Reinforcing Layers

In this paper we suggest a method to calculate the first integrals of a special system of the first order of differential equations. Then we use the method for finding the solutions of some differential equations such as, the differential equation of RLC circuit
