Glycerin and urea tests in Meniere's disease. A multifactorial analysis using a quantification method.
By using the quantification method for multidimensional qualitative data, 13 variables were analyzed. The younger the patient, the stronger was the correlation between age and positive glycerin and urea tests. At ages over 50 years no correlation with positive test results was found. The longer the duration of disease, the stronger was the correlation between this duration and a positive urea test. The glycerin test showed no correlation with the duration of the disease. Hearing losses of 40 to 69 dB. were correlated with both a positive glycerin test and a positive urea test. Greater hearing losses were correlated only to a positive glycerin test. Hearing losses less than 39 dB. were not correlated with positive results in either the glycerin or the urea test.
