A clinical chemistry analyzer; hand shows size. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments. [1]
Clinical pathology is a medical specialty that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids, such as blood, urine, and tissue homogenates or extracts using the tools of chemistry, microbiology, hematology, molecular pathology, and Immunohaematology.
Another particular case in 1957 found that an owl's eye appearance was found by two cells mirroring each other, producing the pattern inside the histological case study of tumors. [21] This is essentially what an owl's eye appearance is, however, the symptom did not occur from the presence of cytomegalovirus but from a unique case.
A case report form (or CRF) is a paper or electronic questionnaire specifically used in clinical trial research. [1] The case report form is the tool used by the sponsor of the clinical trial to collect data from each participating patient.
The FDA requires nonclinical laboratory studies on new drugs, food additives, and chemicals to assess their safety and potential effectiveness in humans in compliance with 21 CFR Part 58, Good Laboratory Practice for Nonclinical Studies under the Federal Food Drug and Cosmetic Act and Public Health Service Act. [16]
It was argued that PICO may be useful for every scientific endeavor even beyond clinical settings. [2] This proposal is based on a more abstract view of the PICO mnemonic, equating them with four components that is inherent to every single research, namely (1) research object; (2) application of a theory or method; (3) alternative theories or methods (or the null hypothesis); and (4) the ...
IUPAC made a recommendation in 1991 [1] for the description and measurement of carryover effects in clinical chemistry. The carryover ratio is the percentage of H3 carry to L1 constituting the carryover portion "h". In a design of 3 high samples followed by 3 low samples, h can be calculated as (L1 - mean of L2&L3) / (H3 - mean of L2&L3)
The terms clinical trial and clinical study are synonymous. (ICH E6) Clinical Trial/Study Report A written description of a trial/study of any therapeutic, prophylactic, or diagnostic agent conducted in human subjects, in which the clinical and statistical description, presentations, and analyses are fully integrated into a single report. (ICH E6)
