Biochemical tests commonly used to identify Proteus vulgaris include urease test (positive result), indole test (negative result), motility test (positive result), citrate test (negative result), and carbohydrate fermentation tests (positive results for lactose and sucrose, negative result for glucose). These tests together help in confirming the presence of Proteus vulgaris in a given sample.
Based on my own test, Shigella flexneri tests negative for the citrate test.
Yes. I am not sure what test you are talking about, but tests are not always 100% reliable.
Go to the doctor to get a real test.
Yes, Serratia marcescens typically tests negative for citrate utilization in citrate utilization tests. This bacterium lacks the enzyme citrate-permease needed to import citrate into the cell, resulting in a negative citrate test.
It means that either the blood tests were wrong or the home pregnancy test was wrong
Sarcina typically tests negative for the Voges-Proskauer test. This test is used to detect the production of acetoin, and Sarcina species do not produce significant amounts of this compound.
Stop taking more urine tests. Repeat the blood test in two weeks.
Yes. The home tests aren't accurate and only the blood test is the accurate one.
The digital pregnancy tests are the same set up as the basic tests. You will urinate on the test (or dip it in your fresh urine) and it will say positive or negative, but if you were to take the test apart the inside has the strip that will show with the one (if negative) or two (if positive) lines. From my experience, sometimes the test will display a negative reading but the strip will be positive with a faint line so always double test a few days later.
Yes, it is possible to have a positive result on a urine pregnancy test and a negative result on a blood pregnancy test. This could be due to differences in the sensitivity of the tests or the timing of the tests relative to the hormone levels in the body. It is recommended to confirm with a healthcare provider for further evaluation.
you could be. take some more tests
