What anticoagulant is found in a purple top tube?
This tube contains EDTA as an anticoagulant – used for most hematological procedures. These tubes are preferred for molecular tests.
What order should blood tubes be drawn?
The order of draw is based on CLSI Procedures and Devices for the Collection of Capillary Blood Specimens; Approved Standard – Sixth Edition, September 2008. This standard recommends that EDTA tubes be drawn first to ensure good quality specimen, followed by other additive tubes and finally, serum specimen tubes.
What can blood tests reveal?
Overall, a test will indicate specific markers including red and white blood cell counts, blood sugar, hemoglobin, cholesterol and vitamin levels. A test can also reveal the presence of specific diseases. “Blood tests also can help find potential problems early, when treatments or lifestyle changes may work best.

What blood tests detect heart problems?
The most common types of blood tests used to assess heart conditions are:

- Full blood count (FBC) – this measures different types of blood levels and can show, for example, if there is an infection or if you have anaemia.
Would a full blood count show anything serious?
“You could take an armful of blood and you couldn’t do that.” Instead, if your full blood count indicates that a certain blood cell is abnormally high or low, this may indicate infection, anaemia, or other more serious diseases. Depending on the results, the GP may then request more tests to confirm a diagnosis.

|---|---|
| Collection Con | A separate EDTA blood sample is required if FBC, PTH, PV or ESR is also requested. Instructions for Lab Staff: Standard lab processing- No special requirements |
| Sample REQ | Blood |
Why is order of draw important?
The order of draw is necessary to obtain correct biochemical results. EDTA contamination was not evident in blood samples collected by trained phlebotomists. The biochemical alterations are statistically and clinically significant.
Why would I need a repeat blood test?
If a doctor asks you to have a repeat test it is usually because: The result was borderline or unclear – so the doctor wants another sample to monitor the situation or to re-check. The result is abnormal – and the doctor is unable to interpret the result without further tests, so has asked you to come in for more tests
