1. Urinalysis

2. BelL Work
1. If you had a Urinary Track Infection, what blood cell would be elevated in your blood/urine?
2. When you give a urine sample at the doctor’s office, what do they ask you to clean before giving the sample?
3. Can you think of other reasons besides a UTI – that a doctor might want a urine sample?
4. What is the most common nosocomial or HealthCare Acquired Infection?

3. Standard
19) Develop a graphic organizer or concept map to explain the functions of the various departments of a medical laboratory, such as microbiology, chemistry, hematology, blood banking, and urology. Include types of fluid samples and test that are performed in each area with a detail of the precautions involved when handling each.

4. Be able to define a urinalysis Understand how to read a urinalysis
Objective
Be able to define a urinalysis
Understand how to read a urinalysis
Identify reasons a patient may need an urinalysis

5. What is a urinalysis? Urinalysis (UA) simply means analysis of urine.
This is a very commonly ordered test which is performed in many clinical settings such as hospitals, clinics, emergency departments, and outpatient laboratories.
Urinalysis is a simple test that can provide important clinical information, has a quick turn-around time, and is also cost effective.

6. How can we use a UA? Results of a urinalysis may be helpful in:
diagnosing urinary tract infections (UTIs),
diagnosing kidney stones,
screening for and evaluating many types of kidney diseases, and
diagnosing and monitoring the progression of diseases such as diabetes mellitus and high blood pressure (hypertension). 

7. Midstream Clean Catch urine sample
Procedure can differ for men and women
For men, the opening of the urethra (tip of the penis) should be wiped clean with a cleansing wipe before collection is begun.
In women, the area around the urethra also needs to be wiped clean with a cleansing wipe. The woman then spreads the labia of the external genitalia and wipes from front to back.
After the urethra is properly cleaned, the collection may begin by discarding the initial stream of urine into the toilet.
Then, milliliters (ml) of urine may be collected in the provided sterile specimen cup by directly urinating into the cup.
Once an adequate amount is collected, then the remaining urine should be voided in the toilet.

8. Obtaining a ua Have the patient use the mid-stream clean catch method
Immediately use the UA test strip and dip into the urine for 1-2 seconds. Ensure each test pad is covered in urine.
Dry off excess urine
Results should be read within 1 minute

9. Visual inspection 1st step in analysis Assess color, clarity, and odor
A normal urine sample may be reported as clear and yellow without any cloudiness.
Obvious abnormalities in color, clarity, and cloudiness may suggest conditions such as:
dehydration,
infection,
Liver disease, or
muscle breakdown.

10. What do the Results look like?

12. What does the Standard Dipstick UA analyze?
In class we will analyze:
Glucose
Protein
Nitrite pH
Blood
Leucocytes

13. Glucose High levels of glucose in the urine could indicate diabetes
Less reliable than blood analysis
Pregnant women tend to have higher urine glucose levels than women who aren’t pregnant.

14. Protein
Protein normally isn't found in the urine. Fever, hard exercise, pregnancy, and some diseases, especially kidney disease, may cause protein to be in the urine.
Healthy kidneys remove extra fluid and waste from your blood, but let proteins and other important nutrients pass through and return to your blood stream.
When your kidneys are not working as well as they should, they can let some protein (albumin) escape through their filters, into your urine.
When you have protein in your urine, it is called proteinuria (or albuminuria). Having protein in your urine can be an early sign of kidney disease.

15. Nitrites in urine show a UTI is present.
Bacteria that cause a urinary tract infection (UTI) make an enzyme that changes urinary nitrates to nitrites.
Nitrites in urine show a UTI is present.

16. pH The pH is a measure of how acidic or alkaline (basic) the urine is.
A urine pH of 4 is strongly acidic, 7 is neutral (neither acidic nor alkaline), and 9 is strongly alkaline.
Sometimes the pH of urine is affected by certain treatments. For example, your doctor may instruct you how to keep your urine either acidic or alkaline to prevent some types of kidney stones from forming.

17. Blood Blood cells aren't found in urine normally.
Inflammation, disease, or injury to the kidneys, ureters, bladder, or urethra can cause blood in urine.
Strenuous exercise, such as running a marathon, can also cause blood in the urine.

18. WBCs in the urine most likely indicate infection.
Leukocytes
WBCs in the urine most likely indicate infection.
