A titre is a method used to find the concentration of a given solution by Titration. It is used in the filed of Chemistry as an analyticla tool for finding the concentrations. It is also used in blood tests. A titre in a blood test measures the concentration of antibody in the blood of a human. This test is normally performed to find out if an individual has developed immunity to any particular diseases by detecting the essential concentration of antibodies in his/her body. Titres are also used to check the concentration of viruses or bacteria in the blood. The titer of an antibody is associated with the number of times one can dilute a sample of blood and still detect the antibody. The term titer, also refers to the strength or concentration of a substance in a solution.
Titers are generally expressed in a ratio, which is how many times they could dilute the blood prior to finding antibodies to any further extent. If the lab was able to dilute it two times, and then could not find any more antibodies, that would be expressed as a titer of 1:2. If they could dilute it a thousand times before they couldn't find any antibodies that would be a titer of 1:1000.
There are two major types of titer testing that can be performed. They are:
A number of conventional serological tests make use of the physical titre principle. Serological tests may be performed for diagnostic purposes when an infection is suspected, in rheumatic illnesses, and in many other situations, such as checking an individual's blood type. These tests can in general be read visually, which makes them quick and economical. The explanation of serological titers is directed by reference values that are specific for the antigen or antibody in question, for instance, a titer value of 1:32 may be below the cut-off for one test but above for some other.
Antibody testing is a common use of titre testing. An antibody is a unique variety of protein made by the immune system to battle against infection. Various antibodies that are usually tested comprise measles, mumps, rubella, varicella or chicken pox, polio, hepatitis B and C. For an individual to be immune to a particular disease, he/she should have antibodies to the disease producing agent in his/her blood. These antibodies can arrive from earlier exposure to an illness producing bacteria or virus, or from vaccination. Antibody levels need to attain concentrations that are specific to each and every disease or illness, for immunity to be there. The information that the titre testing offers can be valuable to a greater extent. It can aid the doctors and physicians to conclude whether vaccination or booster shot would be effectual. The other thing in which titre can be useful is to find out if a person who was exposed to a disease-causing agent achieved immunity from exposure otherwise he must be vaccinated. In case, if the vaccination records are missed or lost somewhere, a titre can be used to confirm the immunity. This reduces the requirement for extra vaccinations.
For fat, the titer of is the temperature, in degrees Celsius, at which it hardens. The higher the values of the titer, the harder the fat would be. This titer is used for finding out whether an animal fat is well thought-out to be tallow, a rendered form of beef or mutton fat (titer higher than 40 degree C) or a grease, which is got from used cooking oil from the fast-food industry (titer below 40 degree C).
