The Vidal test is used to detect typhoid fever by identifying specific antibodies in the blood. In your results, TO (Typhoid O) is 40, TH (Typhoid H) is 80, AO (Paratyphoid A O) is 40, and AH (Paratyphoid A H) is 320. The elevated TH and AH values suggest a likely active infection, particularly with Salmonella paratyphi A or typhoid fever, while the lower TO and AO levels indicate a lesser or resolved response. It's important to consult a healthcare professional for proper interpretation and guidance based on these results.
If the paired differences are normal in a test of mean differences, then the distribution used for testing is the
the q test go to http://en.wikipedia.org/wiki/Q-test
Normal distribution, often represented as a bell curve, is a statistical concept where a trait's values cluster around a central mean, with symmetrical tails extending in both directions. In this distribution, most occurrences take place near the mean, and the likelihood of extreme values decreases as they move further away from the center. This pattern is commonly observed in many natural phenomena, such as height or test scores, where variations are influenced by multiple factors. The characteristics of normal distribution are defined by its mean and standard deviation, which determine the curve's shape and spread.
Whereas a t-test is used for n30, where n=sample size. n < 30 or n > 30 is not entirely arbitrary; it is intended to indicate that n must be sufficiently large to use the normal distribution. In some cases, n must be greater than 50. Note, both the t-test and the z-test can only be used if the distribution from which the sample is being drawn is a normal distribution. A z-test can be used even if the distribution is not normal (but is not severely skewed) if n>30, in which case, we can safely assume that the distribution is normal.
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
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.
widal test.
In Widal test, you measure the antibodies. It takes minimum one week to develop the antibodies of typhoid bacteria.
Vidal (originally- Widal) test related to Typhoid...To diagnose typhoid this test is being done by pathologists..
When using the Widal test for typhoid, the AH and BH should be titers of greater or equal than 1:40 and 1:160 respectively for diagnostic purposes.
mywadil test is 1/160 of Para - typhi AH
Widal test is negative in incubatory carrier. Widal test is always positive in chronic carrier.
As this test is positive, it clearly means that you have typhoid.
my test got both 1.80 what is happening to me
