That depends! It depends on how much ice you have! If you have one kilogram of water, and then freeze it you will have one kilogram of ice. If you are thinking about density (how much volume one kilogram of ice occupies) then it expands as it freezes. 1 litre/gallon of ice weighs less than an idâ¦.
Urine tests are typically used to detect the following STDs: Gonorrhea; Chlamydia; Trichomoniasis; Some doctors also use swabs to collect samples of bodily fluids for testing, a practice that has become less common as accurate blood and urine tests have become available. What do they test for in a STD test?
Chlamydia and gonorrhea tests detect the actual bacteria in the sample. Some tests use a urine sample or cervical swab. If the test is positive, the person has a current STD infection that requires treatment. The syphilis test is a blood test. It detects an antibody produced by the body in response to the infection. The test does not distinguish between a current or past infection and, if it is positive, confirmatory testing will be required.
