What to do before your test

Your pre-testing instructions will depend on the test you’re having, but the most important thing to do is drink plenty of water before your test – unless your GP has given you a reason not to. This will make it easier for our team member to conduct your blood test.

In some cases, you may be required to fast before your test. This means you will not be able to eat or drink for a set period of time. Fasting is necessary for some tests because some foods and drinks can affect your results.

Your doctor will advise if you are required to fast for your blood test.

A quick guide to fasting

Pathology testing for children - Paediatric Collections

When taking your child for a blood test, it is a good idea to explain why the test is necessary, and exactly what is involved. Often bringing a favourite toy, book or colouring activity can help your child feel more comfortable.

Children over the age of 12 years can have their collection performed at any of our centres. For children aged from 1 to 6 years, we have specialised paediatric collection centres with collectors who have been trained in paediatric care.

To find one of these, select “Paediatric Collection (1 to 6 years)” from the “Any test” drop-down menu in the search criteria.

Please call the collection centre you plan to attend ahead of time and make an appointment.

Sometimes your child or baby may require a urine sample to be collected for testing. Please see Urine Collection (Paediatrics) below for further information.

Pre-test collection information

The following pre-test collection information will ensure the specimen you provide to Western Diagnostic Pathology is in the condition necessary for correct examination and accurate result reporting.

Your doctor has requested a 24 hour blood pressure study. This test involves wearing a blood pressure monitor for 24 hours. As this test requires you be fitted with a monitor you will need to contact your chosen Western Diagnostic Pathology clinic to make an appointment.

Screening for Group B Streptococcus (GBS) is performed on pregnant women in their third trimester. 

GBS is a bacterium and a normal part of vaginal and gastrointestinal flora that is present in between 14% and 25% of pregnant women. 

However, it can (rarely) cause life-threatening septicaemia or meningitis in a newborn child. It can also cause infections in pregnant women and immunosuppressed people.

To determine if you are currently colonised with GBS this test requires you to collect a swab from your vagina and then from your anus. This specimen will be sent to the laboratory where screening will take place and the result will be given to your health care provider, who will then discuss the result with you.

Collection instructions

The staff will provide you with gloves and one swab to use while collecting your specimen.

STEP 1: Wash your hands and put on the gloves. Find a comfortable position, either lying on the bed or standing.

STEP 2: Open the packaging and remove swab by holding the plastic end of the swab.

STEP 3: Insert cotton end of the swab 2 cm into your vagina and remove. Using the same swab, insert cotton end 1 cm into your anus and remove.

STEP 4: Take the plastic tube from the packaging and remove cap. Place swab into the tube and replace the cap, ensuring it is firmly in place.

STEP 5: Label the plastic tube with your name, date of birth, today’s date and the time that you collected your sample.

STEP 6: Remove your gloves and dispose of them in a bin, wash your hands.

LIMITATIONS OF TEST

This screening test only tests for the chromosomal abnormalities requested. Normal test results do not eliminate the possibility that your pregnancy may have other chromosomal abnormalities, birth defects, or other conditions. A normal result does not guarantee a healthy pregnancy or baby. This test has limitations including false positives and false negatives. For these reasons it is strongly recommended that no irreversible clinical decisions be made based on these screening results alone.

This is a special test which is only performed at selected Western Diagnostic Pathology collection centres. To find a centre which performs this test select “Non-invasive Prenatal Test (NIPT), Non-invasive Prenatal Test Plus (NIPT) or Non-invasive Prenatal Test (NIPT) Generation 46” from the “Any test” drop down in our Collection Centre search, or alternatively call 08 9317 0999.

You will need to make an appointment for this test. This test involves having baseline blood sample taken in first morning, taking 1mg of Dexamethasone tablets at night, and then having a second blood sample collected the next morning.
Note: If you have any significant allergies, especially to steroids, please consult with your doctor before returning for the test.

Your doctor has requested a sputum test and the laboratory requires a specimen of inflammatory secretions (phlegm), which has been coughed up from the lungs and lower air passages.

This sputum is usually thick and opaque, and may vary in colour (grey, green or yellow). Thin, watery saliva is not suitable for testing.

If chest physiotherapy treatment is being given, it is preferable for the physiotherapist to help collect a suitable sample.

If at home, it may be useful to arrange pillows over the side of a bed and lie on them head downwards for about 10 minutes to drain the sputum from the lungs. The most adequate sample may be obtained early in the morning on rising.

Rinsing the mouth out with water first may make the collection easier, especially if the throat is dry and the sputum is very sticky.
A deep breath in, followed by a strong cough, will help to carry the sputum into your throat. You can then cough the specimen into the container provided.

If the sample appears thin and watery with food particles, it is saliva. Please obtain another sterile container from a Western Diagnostic Pathology collection centre and collect again.

If you are unable to get the sample to a Western Diagnostic Pathology collection centre on the day the specimen is produced, please refrigerate it.

Urine Testing

It is important to ensure that the bottle is kept upright at all times as some bottles contain corrosive additives.
Please ask for two bottles if you think that one will not be sufficient.

FOR EXAMPLE:

6.00AM DAY 1
Empty bladder and discard the urine into the toilet. Pass all urine for the next 24 hours into the bottle.

6.00AM DAY 2
Next morning, empty bladder into the bottle. This will complete the collection.

Your doctor requested a urine sample for examination. This test is very important to assess your health and will only give useful results if collected properly. Normal body secretions may alter the results, so it is necessary to clean the area where urine is passed thoroughly. Please follow these guidelines. Do not hesitate to ask for assistance.
