Our phlebotomists will not take blood from children younger than 16 years old.

Our phlebotomists will not take blood from children younger than 16 years old.

We do not recommend attempting to take a finger-prick sample from anyone younger than 12 years old. However, this type of sample is likely to be easier to take than a draw from a vein. Parents or guardians are advised to use their own discretion. 

As quickly as possible – blood samples can deteriorate over time so do not post on weekends, bank holidays and at times when there is likely to be a delay. 

We have a variety of needle sizes in store to make your blood taking experience comfortable.  

All tubes must be filled as much as possible, ideally to the top of the tube. This is to ensure that there is sufficient sample to provide a result. Please use as many lancets as necessary and follow the instructions provided with your kit.

Haemolysed blood means that the red blood cells have been damaged during the blood collection or transport processes. Heat can cause it too. Haemolysed blood can be difficult to test and can mean that the blood test needs to be repeated. 

Unfortunately, there is no way to completely guarantee that a sample will not clot. To avoid clotting, make sure you gently turn the tube over a couple of times to mix the blood if it has a green or purple top. 

All our results include a GP-reviewed report with an interpretation and explanation of your results. Blood tests alone are not a substitute for seeing a doctor, particularly if you are feeling unwell. You should not make a diagnosis or start any treatment without a consultation with a doctor or a suitably trained health care professional. All results need to be interpreted in the context of the rest of your health and this can only really be determined with a full clinical history and examination. For further information regarding your results, we recommend you contact your GP. 

This means that the result is difficult to interpret as it is borderline between positive and negative. It is difficult to say whether this is due to a past infection or the start of a new one. We recommend that you repeat the test as soon as possible. 

Unfortunately, on some occasions our laboratory cannot perform a test on a sample. This is due to a sample falling short in terms of quality, volume or some other eligibility criteria. In these cases, the laboratory may need to reject the sample, and not carry out processing. Sometimes the laboratory is able to compensate for a suboptimal sample, although this often leads to delays and turnaround times may be affected.  

Results will be sent the day after your sample arrives at the laboratory. For allergy testing and sexual health profiles, results will be sent 2-3 days after your sample arrives with us. 

The normal ranges for tests can vary over time because we constantly revise the ranges to take into account any change in our testing equipment, chemical reagents used in the testing process and the analysis techniques.
