The shape of salt crystals is influenced by temperature and rate of evaporation. Higher temperatures and slower evaporation rates tend to produce larger salt crystals, while lower temperatures and faster evaporation rates result in smaller crystals.
A positive test for Bence Jones protein in urine indicates the presence of abnormal proteins, which can be a sign of multiple myeloma or other related conditions. A negative test means that there are no detectable Bence Jones proteins in the urine. It is important to interpret the results in conjunction with other clinical findings to make an accurate diagnosis.
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.
Mixing water with urine will dilute the urine sample, potentially affecting the accuracy of the urine test results. The concentration of substances in the urine, such as drugs or metabolites, may be lower than expected, leading to false-negative results. Dilution of the urine sample is generally considered an attempt to cheat or manipulate the test.
No, a urine pregnancy test measures the same hormone (hCG) as a blood test, so they should typically give consistent results. If a blood test is positive, a urine test should also show a positive result.
The distance between centers of positive and negative ion in the ionic crystals vary from one structure to another.
Yes, a positive testing urine test will show faster than a negative urine testing.- Personal experience (I have had many urine tests) use "sure jell" and you will pass everytime!!!!! look it up on google.
NO
not very likely
No, not all crystals are neutral. Crystals can have their own unique energetic properties and vibrations that can either be positive, negative, or neutral. It's important to choose crystals that resonate with your own energy and intentions.
Normally crystals do not have electrical charge.A few types of crystals (e.g. quartz) will develop an electrical charge across them when placed under mechanical stress. This property is called piezoelectricity. But the positive and negative charges are on opposite sides of one crystal, not on two different crystals.Perhaps you were actually thinking of something that has nothing to do with science or electricity when you asked this question.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The rates of false negative and false positive chlamydia tests for various types of tests are as follows (see related link):Becton-Dickinson NAAT female urine: 1% false positive; 19.5% false negativeGen Probe NAAT female urine: 1.1% false positive; 5.3% false negative
Keeping a urine sample refrigerated allows the pH to aid in identification of crystals. Crystals form when urine is kept cool.
When positive ions and negative ions are nearby they are attracted and pair up building an Ionic Crystal.
