What is an end point in clinical trials?
Listen to pronunciation. (END-poynt) In clinical trials, an event or outcome that can be measured objectively to determine whether the intervention being studied is beneficial. The endpoints of a clinical trial are usually included in the study objectives.
What are the tests done in clinical chemistry?
Specimens tested in clinical analysis
- Serum. Serum is the most common specimen tested – it is obtained by centrifugation of coagulated blood.
- Plasma. Plasma is obtained by centrifugation of uncoagualted blood.
- Urine.
- Cerebrospinal spinal fluid (CSF)
- Carbohydrates.
- Lipids.
- Enzymes.
- Hormones.
What are endpoints in pharma?
Clinical endpoints or clinical outcomes are outcome measures referring to occurrence of disease, symptom, sign or laboratory abnormality constituting a target outcome in clinical research trials. The primary endpoint of a clinical trial is the endpoint for which the trial is powered.
What is the difference between endpoint and outcome?
The term outcome usually refers to the measured variable (eg, peak volume of oxygen or PROMIS Fatigue score), whereas an endpoint refers to the analyzed parameter (eg, change from baseline at 6 weeks in mean PROMIS Fatigue score).
What is a primary endpoint example?
A primary endpoint is the main measurement a trial is trying to assess. It answers the most important question in the trial. For example: In a weight loss study: What is the average weight loss after six months? In a trial for a new cancer drug: What is the average increase in survival time?
What is standard in clinical chemistry?
What is a Standard? Standards are materials containing a precisely known concentration of a substance for use in quantitative analysis. A standard provides a reference that can be used to determine unknown concentrations or to calibrate analytical instruments.
What are the important of clinical chemistry?
The function of clinical chemistry and laboratory medicine is to perform qualitative and quantitative analyses on body fluids such as blood, urine, spinal fluid, faeces, tissue and other materials.
What is another name for endpoint?
What is another word for end point?

| goal | tape |
| stopping place | resting place |
| finish line |
What are exploratory endpoints?
Exploratory. Exploratory endpoints may include clinically important events that are expected to occur too infrequently to show a treatment effect or endpoints that for other reasons are thought to be less likely to show an effect but are included to explore new hypotheses.
What is the end point reaction method in chemistry?
Whereas, the end point reaction method is an analysis method used in clinical chemistry to determine the total amount of analytes consumed during the progression of a reaction. In this method we measure the total amount of analytes that participate in the reaction. Furthermore, the time period taken for this reaction is 5 to 15 minutes.
What is a clinical endpoint in a clinical trial?
Clinical endpoint • In a clinical research trial, a clinical endpoint generally refers to occurrence of a disease, symptom, sign or laboratory abnormality that constitutes one of the target outcomes of the trial. 14. Mortality • It is important to note that endpoints may include adverse reactions that reflect on the safety of the treatment.
How to estimate analytes in clinical chemistry?
Clinical Chemistry Methodologies: Generally, three methods are followed for the estimation of various analytes in clinical chemistry. They are: 1. End Point method or end poind chemisty 2. Fixed time method or fixed time chemistry 3. Kinetic method or Kinetic Chemistry
What are the different reaction methods used in clinical chemistry?
There are three main reaction methods that we use in clinical chemistry for the analysis of enzymatic reactions; kinetic method, fixed time method and end point method.
