What are bloods?

‘Bloods’ refer to blood, removed from a patient and sent for laboratory analysis. The most common site of accessing blood is from peripheral veins, commonly the antecubital fossa in the arm. Blood can also be obtained from arteries (usually deeper in the body) or directly from some organs. Numerous blood tests are available and the doctor ordering the test will do so in order to facilitate making a diagnosis, excluding some conditions, monitoring the progress or effectiveness of treatment or monitor the progress of an untreated condition or abnormality. Blood test results need to be assessed in the context of an individual’s particular circumstance. It is possible that the results of one set of bloods to indicate a requirement for further bloods to be taken and analysed. Blood test results should always be interpreted using the ranges provided by the laboratory that performed the test.

Blood tests in gynaecology

For the majority of blood tests, blood is usually obtained from the patient’s vein (venous blood). Sometimes, arterial blood is required. The most common area for venous blood to be obtained is from the anterior aspect of the elbow (the antecubital fossa). For arterial blood, the most common site is the wrist. Other sites for obtaining blood include vessels in the feet, groin and neck.

Blood for most types of analysis can be drawn at any time of the day, and generally, you will be advised to have the blood taken during office hours. Blood for some tests, however, need to be drawn at a particular time. ‘Fasting’ bloods require that you do not eat for a given period of time because nutrients in food and drinks are absorbed into the blood stream and could influence factors measured by certain tests. The most common type of fasting blood test measures levels of lipids or glucose. Your doctor will advise you about the exact fasting time. If possible, schedule your blood test for the early morning to minimize the length of time you’ll have to go without food. If you are to have bloods for Group & Save or Cross match as preparation for intermediate or major surgery the haematology labs usually require these to be done within 7 days of surgery. Check with the lab or your doctor.

Some blood tests are time dependant; either time of day or time of month. These blood tests are typically for assessment of hormones that have either a diurnal variation (i.e. cortisol) or level influenced by the time of the month (i.e. progesterone level).
