Glossary Term
A process where a rotating machine exposes a specimen to centrifugal force. This process can be used to remove moisture from a specimen, to subject an organism to increased gravitational forces, or to separate the components of heterogeneous mixtures based on density differences.
Glossary Term
A machine that uses centrifugal force to separate heavier substances from lighter ones, for removing moisture, or for simulating gravitational effects.
Glossary Term
The nonstaining primary constriction of a chromosome which is the point of attachment of the spindle fiber; provides the mechanism of chromosome movement during cell division; the centromere divides the chromosome into two arms, and its position is constant for a specific chromosome: near one end (acrocentric), near the center (metacentric), or between (submetacentric).
Tests
The determination of the amount of centromere IgG antibody present in a biological specimen.
Glossary Term
The process by which a person demonstrates specific knowledge, skills, or abilities in the view of a certifying body. Similarly, the process by which a product or process can achieve certification indicating its suitability for a specific purpose.
Tests
The determination of the Charcot-Leyden crystals present in a sample.
Indicators
This gene is involved in the negative regulation of cell growth.
Glossary Term
Chi-square test is a statistical test for testing the null hypothesis that the distribution of a discrete random variable coincides with a given distribution. It is one of the most popular goodness-of-fit tests.
Tests
The determination of the amount of the Chikungunya virus antibodies in a biological sample.
Tests
The determination of the amount of Chlamydia pneumoniae IgM antibody present in a sample.
Tests
The determination of the Chlamydia trachomatis antigen present in a sample.
Glossary Term
The genetic material of the nucleus, consisting of deoxyribonucleoprotein, which occurs in two forms during the phase between mitotic divisions: 1) as heterochromatin, seen as condensed, readily stainable clumps; 2) as euchromatin, dispersed lightly staining or nonstaining material. During mitotic division the chromatin condenses into chromosomes.
