Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one. A one-to-one function is a function where every element of the range correspons to exactly one element of the domain. Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
false!
what is the relationship between chest circumference and lung function test
f(x) = x2 This is a function by the vertical line test because a vertical line drawn through this function will only intersect the function at one point
What is false positive in widal test
The main difference between the Widal slide test antigen and the Widal tube test antigen lies in the method of reaction visualization. In the Widal slide test, the reaction is observed on a glass slide under a microscope, whereas in the Widal tube test, the reaction is seen in small test tubes. Both tests detect antibodies against specific Salmonella antigens, but differ in their setup and visual interpretation.
I mean widal test result positive after treatment
Isolated Widal test reading does not have much clinical significance. Rising titre of Widal test done one week apart, in a febrile patient, indicates typhoid fever. You can have such rising titre of Widal test in healthy patient, after dose of typhoid vaccine.
1:80 titre is significant for determination of widal positive.
widal test
To a certain extent yes.The post antibiotics Widal Test will have Low titers of agglutinins.Hence the test may be reported as False Negative.
The blood test for typhoid is called the Widal test. It detects antibodies in the blood against the Salmonella typhi bacteria, which causes typhoid fever.
widal test.
manual test of widal method
Widal test is negative in incubatory carrier. Widal test is always positive in chronic carrier.
In Widal test, you measure the antibodies. It takes minimum one week to develop the antibodies of typhoid bacteria.
