Final outcome ÷ possible outcome X100 (eg. If I got 23 out of 30 for a test then ---> 23÷30 X100 = 76.66= 77% ) hope this helped... :]*
In assays, or medical tests, both qualitative and quantitative tests occur. The qualitative test identifies the presence or absence of the pathogen or toxin (or other molecule) being tested for, while the quantitative test hopes to measure how much of that particular substance is in the body.
The underlying principle is that the square of an independent Normal variable has a chi-square distribution with one degree of freedom (df). A second principle is that the sum of k independent chi-squares variables is a chi-squared variable with k df.
To test for T-2 mycotoxins in environmental samples, the technique of high-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS) is commonly employed. This method allows for the separation, identification, and quantification of T-2 mycotoxins with high sensitivity and accuracy. Additionally, enzyme-linked immunosorbent assay (ELISA) can also be used as a rapid screening tool for detecting T-2 toxins in various matrices.
PCR assays can be both qualitative and quantitative, depending on the method used. Qualitative PCR, often referred to as conventional PCR, detects the presence or absence of a specific DNA sequence. In contrast, quantitative PCR (qPCR or real-time PCR) measures the amount of DNA, providing information on the quantity of the target sequence in a sample. Thus, PCR can serve both purposes based on the specific assay design.
The principle of complement-fixation test involves the detection of antibodies by measuring the ability of a patient's serum to fix and consume complement in the presence of a specific antigen. If antibodies are present in the sample, they will fix complement, leading to a decrease in complement activity that can be detected. This test is often used to diagnose infections such as syphilis and certain viral diseases.
The CFT full form of civil work is Complement Fixation Test.
Complement-fixation Test
Laboratory tests. a complement fixation (CF) test is based on.if antibodies are formed in the body in response to the illness, then the antigen and the antibody will form complexes.The serum complement fixation.confirms the presence of antibodies.
For a complement fixation test, you will need serum samples from the patient being tested, heat-inactivated complement serum, specific antigen-antibody complexes, an indicator system to visualize complement activity, saline or buffer solutions, and control samples. The test is used to detect the presence of specific antibodies in the patient's serum by measuring the level of complement fixation.

Complement Fixation Test is the full form of CFT. It is usually used in civil work.
Patient history and physical examination. serological (immunological) tests are used widely .the Weil-Felix test. a complement fixation (CF) test. the fluorescent antibody test.
assay test of sodium acid citrate
A number of tests are used for Valley fever: chest x-rays, biopsy, sputum exam, and complement fixation assays.
assay
There are several blood tests that can be used to confirm the diagnosis of LGV. The most commonly used are the complement fixation (CF) test and the microimmunofluorescence (micro-IF) tests.
