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?
One exception would be Trichomonas, a motile parasite, which could be seen swimming around in the urine when viewed under a microscope; however, trichomonas is probably the least of your worries. You CAN test urine for chlamydia and gonorrhea, but your doctor has to SPECIFICALLY ask for these tests. A special test for DNA will pick up these STD's, and it is NOT performed in a routine check for a urinary tract infection. As a lab tech, let me tell you that I test HUNDREDS of people a day for STD's.
