Common Laboratory Services For General Medical Checkup

Doctors send their patients to a lab for various services. Results from laboratories help them have a better understanding of their patient’s condition.

 

You may have gone a number of times to a diagnostic center and are familiar with the three most common laboratory services in a diagnostic center: urinalysis, stool analysis, and blood test.

 

Urinalysis

 

Urine tests are done for a variety of reasons. If you are going to undergo a urine test for your medical check up, here are some hints for more accurate results. The medical techs at the lab should inform you of the proper procedure for collection of a sample as well.

 

  1. For males:
    1. A sterile container should be used to collect samples.
    2. The bladder should be moderately full.
    3. The foreskin should be completely retracted.
    4. Tip of the penis should be thoroughly cleansed.
    5. Midstream sample should be collected (halfway through the urinating process).
    6. The sample should fill at least half of the container.
    7. The sample should be brought immediately to the laboratory.

 

  1. For females:
    1. A sterile container should be used to collect samples.
    2. Urethral opening should be thoroughly cleansed.
    3. Lips of the vagina should be spread.
    4. Midstream sample should be collected (halfway through the urinating process).
    5. The sample should not be contaminated with menstrual blood and vaginal discharge.
    6. The sample should be brought immediately to the laboratory.

 

Stool Analysis

 

A stool analysis is a series of tests done on a stool (feces) sample to help diagnose certain conditions. Here are some reminders for stool sample collection:

 

  1. Clear and wide-mouth bottle should be used.
  2. Small amount of stool should be collected. The container should not be overfilled.
  3. The specimen should not be contaminated with urine or toilet paper.
  4. The container should not be sealed tightly to allow the escape of gas.
  5. The sample should be brought immediately to the laboratory.

 

Blood Analysis

 

Another common test in a diagnostic center is the blood test. Collection of blood samples is a standard procedure carefully performed by well-trained medical technologists. Because most doctors ask for a blood test to be done during a medical check up, it is wise to be informed of some side effects of the process. Most patients do not suffer from blood test side effects, but some patients experience some discomfort.

 

  1. A Hematoma or lump accompanied by bruising may occur during the collection of a blood sample. This is commonly caused by blood seeping out of the vein into the surrounding tissue as the needle passes through the underside of the vein. If this happens to you, just apply pressure for up to 5 minutes and then apply ice for another 5 minutes.
  2. Bruising may also occur at the venipuncture site. This is due to blood leaking from the hole in the vein into the surrounding tissue. Apply pressure for at least three minutes to the affected site immediately after the collection to help prevent bruising.
  3. Some patients actually faint inside a diagnostic center during a blood test. If you are one of them, inform the staff before the blood test so they can assist you. It is advisable to stay in the diagnostic center until you feel better.

    I know that there is an increasing number of companies that do drug screenings via Urinalysis. It’s good to know that midstream samples should be collected for accurate analysis by lab services. This way you only have to take the test once and don’t need to go back. I’ll remember your tips the next time I need to be tested.
