Dear beckyy
When the sample provided to be tested is not satisfactory , how can the results be satisfactory. The answer to your question is yes as the hormones if in sufficient quantity are bound to give positive results.

thanks for choosing health care magic.You mean to ask that one patient who was pregnant and undergone urine test and other one has collected in same bottle without washing it and what could happen.See any test helps in diagnosis but it is not only tests which gives diagnosis.Patients complain and symptoms comes first and then the test results.Yes but your question ,yes there is a possibility because a drops of urine which are applied on the strip if it contains the hormone then test will come reactive.But if you have missed period and having other symptoms go for test again and clear the confusion.
