What are the 4 types of urine collection tests?
The urine sample is examined under a microscope to: Check if there are any cells, urine crystals, urinary casts , mucus, and other substances….How the Test is Performed
- Red blood cell urine test.
- Glucose urine test.
- Protein urine test.
- Urine pH level test.
- Ketones urine test.
- Bilirubin urine test.
- Urine specific gravity test.
What is the best method to collect the urine specimen?
To collect the urine sample:
- Keeping your labia spread open, urinate a small amount into the toilet bowl, then stop the flow of urine.
- Hold the urine cup a few inches (or a few centimeters) from the urethra and urinate until the cup is about half full.

Urine tests can help detect diseases of the urinary system as well as metabolic diseases like diabetes or liver disease. The color, odor and amount of urine can already indicate whether something is wrong.
What type of urine specimen is collected for urinalysis?
Specimen collection: 1. Routine or random sample: The patient is given a non-sterile collection container and instructed to collect a midstream specimen in the container. This type of specimen is routinely used for urinalysis and may not be used for a culture and sensitivity.
What is the recommended procedure for collecting a 24 hour urine procedure?
A 24-hour urine sample is needed: On day 1, urinate into the toilet when you get up in the morning. Afterward, collect all urine in a special container for the next 24 hours. On day 2, urinate into the container when you get up in the morning.
What is the specimen of choice for routine urinalysis?
First Morning Specimen This is the specimen of choice for urinalysis and microscopic analysis, since the urine is generally more concentrated (due to the length of time the urine is allowed to remain in the bladder) and, therefore, contains relatively higher levels of cellular elements and analytes such as protein, if …
What are the most common methods of preservation of urine specimen?
The commonly used urine preservatives include boric acid, hydrochloric acid, acetic acid, and oxalic acid. Certain buffers and bicarbonate salts may also be used for specific measurands. Laboratories need to evaluate the effectiveness and potential interference of preservatives.
What are urine reagent strips?
Urine Reagent Strips are firm plastic strips onto which several separate reagent areas are affixed. The test is for the detection of one or more of the following analytes in urine: Leukocytes, Glucose, Ketone (Acetoacetic acid), Bilirubin, Blood, Specific Gravity, Protein, Urobilinogen, Nitrite, Ascorbic Acid, and pH.
When is the best time to collect urine for urinalysis?
Random Urine Collection for Urinalysis
- Urine for urinalysis may be collected at any time, at the lab or in your home.
- It is preferred that you collect a specimen first thing in the morning, because the first morning urination is more concentrated and likely to yield the best results.
What type of urine specimen is preferred for routine chemical testing?
The first urine voided in the morning is preferred because it has a more uniform volume and concentration and a lower pH, which helps preserve the formed elements. If it is not possible to obtain a first morning sample, the time of the sample should be noted on the test request form and in the patient’s records.
