ambiguity tolerance the ability to withstand conflicting or complex situations without undue psychological stress.
drug tolerance a decreasing response to repeated constant doses of a drug or the need for increasing doses to maintain a constant response. See also drug dependence and habituation.
immunologic tolerance specific nonreactivity of lymphoid tissues to a particular antigen capable under other conditions of inducing immunity.
standing tolerance the amount of time an individual is capable of maintaining an erect, upright position.
tolerance test
1. an exercise test to determine the efficiency of the circulation.
2. a test to determine the body's ability to metabolize a substance or to endure administration of a drug.

tolerance test

1 an investigation of the ability of the body to metabolize a drug or nutrient, as in a glucose tolerance test.
2 a physical activity drill administered to evaluate the efficiency of blood circulation or of another body system.

tolerance test

1. Exercise tolerance test, see there.
2. A maneuver in which the ability to metabolize a drug is tested by administration of a small dose thereof.


1. an examination or trial.
2. a significant chemical reaction.
3. a reagent. See also under specific names of tests.

cis-trans test
used in microbial genetics to determine whether two mutations that have the phenotypic effect, in a haploid cell or a cell with single phage infection, are located in the same gene or in different genes; the test depends on the independent behavior of two alleles of a gene in a diploid cell or in a cell infected with two phages carrying different alleles.
critical titer test
the titer of a test at which the patient is judged to have reacted positively to the test.
diazo test
a group of tests for bilirubin conjugates in urine and therefore suitable for the detection of biliary and hepatic disease. Based on the combination of bilirubin with a stable diazonium compound.
exact test
a statistical test based on the exact distribution of the data under the null hypothesis, rather than on a normal approximation.
hypothesis test
the method by which a hypothesis is judged.
sodium sulfanilate clearance test
test station
set up by the government or a cooperative organization for the purpose of testing individual livestock provided by farmers for productivity in terms of egg production, milk yield, weight gain. The feeding and measurement are under the control of the station.
statistical test
used to decide between two hypotheses.
surrogate test
an indirect test, e.g. milk cell count.
tolerance test
1. an exercise test to determine the efficiency of the circulation.
2. determines the body's ability to metabolize a substance or to endure administration of a drug, e.g. insulin tolerance test.
triglyceride absorption test
see fat absorption test.
urine concentration test
see water deprivation test.
a dexamethasone suppression test followed by an ACTH response test; the name refers to the change in plasma cortisone levels, first depressed then elevated, which if plotted on a graph would form a V.


the ability to endure without effect or injury.

drug tolerance
1. decreased susceptibility to the effects of a drug due to its continued administration.
2. the maximum permissible level of a drug in or on animal feed or food at any particular time relative to slaughter.
high-dose tolerance
in immunology, that induced by the intravenous administration of high doses of aqueous proteins.
immunological tolerance
specific nonreactivity of the immune system to a particular antigen, which is capable under other conditions of inducing an immune response. There is, under normal circumstances, tolerance to self-antigens; identical (monozygotic) twins and dizygotic cattle or sheep twins where there has been placental fusion and exchange of bone marrow stem cells are also tolerant of each other's tissues. Allophenic mice, that is mice produced by fusion of blastocysts from different mice are also tolerant of both 'parents'. The administration of antigens either at high or low dose and infection with certain viruses during critical early stages of immunological development may also induce tolerance.
tolerance level
the concentration of a drug or chemical permitted by law to be present in human food.
tolerance limits
the numerical limits within which a previously identified proportion of values of a variable, or observations in a population, can be expected to occur.
low-dose tolerance
that induced by repeated administration of low doses of the antigen.
oral tolerance
that induced by oral administration of the antigen.
the non-reactivity of the immune system to self-antigens.
tolerance test
see tolerance test.
zero tolerance
when no detectable amount of a chemical substance is permitted in human food.

Patient discussion about tolerance test

Q. When will I have the Glucose Tolerance Test? I am pregnant and wanted to know when I need to have the Glucose Tolerance Test and what is the test like.

A. The test is given between week 24 and week 28 of the pregnancy. First you drink glucose, which is very sweet. You can mix it will water to help it go down easier. Then, after an hour you will have a blood test to check your glucose levels.

Q. What Do my Oral Glucose Tolerance Test Results Mean? I had an Oral Glucose Tolerance Test last week. I am 26 weeks pregnant. The results I got are 132 mg/dL. What does this mean?

A. If your blood glucose level was greater than 130 mg/dL, your provider will likely recommend you take another diabetes screening test that requires you to fast (not eat anything) before the test. During this second test, called the 100-gram oral glucose tolerance test, your blood glucose level will be tested four times during a three-hour period after drinking the cola-like drink. If two out of the four blood tests are abnormal, you are considered to have gestational diabetes.
