What is a urinalysis?
A urinalysis is simply an analysis of the urine. It is a very common test that can be performed in many healthcare settings including doctors' offices, urgent care facilities, laboratories, and hospitals.
It is performed by collecting a urine sample from the patient in a specimen cup.
Usually only small amounts (30-60 ml's) may be required for urinalysis testing.
The sample can be either analyzed in the medical clinic or sent to a laboratory
to perform the tests. Urinalysis is abbreviated UA.
Urine can be evaluated by its physical appearance (color, cloudiness, odor,
clarity), or macroscopic analysis. It can be also analyzed based on its chemical
and molecular properties or microscopic assessment.
Urinalysis is ordered by doctors for a number of reasons, as follows:

My son was diagnosed with henoch-schonlein purpura (HSP) when he was five. He woke up one morning and told me his ankle was hurting and that he couldn't walk. There was a tiny pinkish spot in the ankle area. I asked him to recall what he had done the day before thinking that somehow it was just sore from some activity. He said he jumped out of a tree and may have bumped it. I carried him to Urgent Care to get a foot x-ray. As it turned out, there were no broken foot bones. As we waited, the small spot grew from a dime size to a quarter size. The doctor then ran a series of blood tests which came back showing that there was some type of non-specific inflammation in my son's body. He suspected that my son was having an arthritic reaction to the cold and stomach virus he had had the week before. He let us go home but called the Children's ER and informed them that we might show up if things worsened. Between 6 p.m. and 10 p.m., the rash worsened. The red dots had grown together and were all over his ankles. His feet were swollen and very itchy. It was like the blood began to pool under his skin. He still couldn't walk. He also had areas with red dots on his torso, thighs, arms, and scalp. Basically all of his joints were aching and he had a horrible headache. Well, at about 10 p.m. I was picking him up and he screamed out in pain. I raised his shirt to find that his back was swollen the length of his spine. I literally freaked out and rushed him to the ER. By midnight, the ER docs diagnosed him with HSP. I think the Urgent Care doc would have diagnosed the HSP had the rash been more prominent earlier. My son stayed the night at the hospital. He couldn't walk for almost 2 weeks. He had to do weekly and then monthly urine tests to monitor whether the HSP was in his kidneys, but nothing ever showed up. He never had to take the Prednisone, just ibuprofen. My son is now 8 and I can still remember almost every detail of that frightening day. He has not had HSP again but every cold he gets worries me and I can assure you that I try to make sure he is always well rested (at least 10 hours of sleep a night) so that his immune system can better fight off viruses.
