The intra-analytical phase refers to the processes that occur during the analysis of a specimen in the laboratory, including sample preparation, analysis, and interpretation of results. It involves activities such as centrifuging, aliquoting, and performing tests on the specimen. Proper handling and processing during this phase are crucial to ensuring accurate and reliable test results.
What else can I help you with?
Is a CBC a pre-analytical or analytical variable?
A CBC (complete blood count) is considered an analytical variable. The pre-analytical phase involves specimen collection and handling before analysis, while the analytical phase involves the actual testing and analysis of the specimen, which includes processing it to obtain results.
What is a phase microscope?
A phase-contrast microscope (or phase-difference microscope or phase microscope) allows better viewing of clear specimens that usually need to be stained before you can make out the various parts. Staining is a time consuming process and kills the cells being viewed. With a phase-contrast microscope, living cells can be studied as they go through the cell division cycle.HOW IT WORKSAs light goes through a transparent specimen, there may not be anything interesting to see. However, the light undergoes phase changes as it passes through the different parts of the specimen. Unfortunately, the human eye does not notice phase changes. A phase-contrast microscope converts these unnoticed phase changes into differences in brightness, which the human eye sees very well. The darker and lighter parts of the specimen make it very visible.This also works on reflected light microscopes.

What concept of microscopy deals with the ability of the specimen to stand out against its background?
Contrast in microscopy refers to the ability of the specimen to be distinguished from its background. Techniques such as staining, phase contrast, and differential interference contrast (DIC) microscopy can enhance contrast in microscopy.
What does the word phase mean in microscopy?
In microscopy, the term "phase" typically refers to phase contrast microscopy, a technique that enhances the contrast of transparent or low-contrast biological specimens by exploiting differences in refractive index within the specimen. Phase contrast microscopy allows for visualization of cell structures and organelles that would otherwise be difficult to see with traditional brightfield microscopy.
Is a CBC a pre-analytical or analytical variable?
A CBC (complete blood count) is considered an analytical variable. The pre-analytical phase involves specimen collection and handling before analysis, while the analytical phase involves the actual testing and analysis of the specimen, which includes processing it to obtain results.
Which phase of laboratory testing is a phlebotomist responsible for?
A phlebotomist is primarily responsible for the pre-analytical phase of laboratory testing. This includes tasks such as patient identification, specimen collection, labeling, and ensuring proper handling and transport of samples to avoid contamination or degradation. Their role is crucial in ensuring the accuracy and reliability of test results.

What are three phases of laboratory testing?
The three phases of laboratory testing are pre-analytical phase, analytical phase, and post-analytical phase. The pre-analytical phase refers to all the steps taken prior to the actual testing of a specimen (e.g. specimen collection, transport, accessioning). The analytica phase includes the actual testing analysis. The post-analystical phase includes test reporting and interpretation.
When was Phase Space - story collection - created?
Phase Space - story collection - was created in 2003.
What is the ISBN of Phase Space story collection?
The ISBN of Phase Space - story collection - is 0-00-651185-6.
What does the phase plate do to the light that has passed through the specimen?
Makes a prizom of colors
What is the most important issue in the data collection phase of research?
Consistency of data collection.
Stage two of the ISSA drawing-in phase is?
Stage two of the ISSA drawing in phase is data collection.

A phase-contrast microscope differs from a brightfield microscope by having a?
Phase-contrast microscope utilizes phase shifts in light passing through a transparent specimen to enhance contrast, making transparent objects more visible without staining. Brightfield microscopes rely on absorption of light by the specimen to create contrast, typically requiring staining to visualize transparent specimens effectively.
