Blood Sample Collection

This procedure will be conducted by one of our fully trained sample collectors, that can come to an address of your choosing anywhere in the UK to take the sample. Alternatively, you may wish to visit one of our walk-in centres to have your sample collected for free. It may be specified in certain legal cases that the sample has to be taken by a neutral third party (usually a GP), in this case AlphaBiolabs will handle everything else involved in the testing process, but the GP may require their own fee.

In cases where a GP or one of our trained staff has taken the sample, the results are legal admissible in court and for other authorities such as the CSA, as they will follow strict procedures to keep the chain of custody throughout the process.

The Reasons For Blood Testing

AlphaBiolabs more commonly utilises buccal swab (saliva) and hair testing wherever possible, which does not require any blood to be drawn at all. However, there are a few tests where a blood sample is required.

An example of this is a Blood alcohol-test such as a Liver Function Test (LFT) or a Carbohydrate Deficient Transferrin (CDT) test, which can be used to analyse a history of alcohol consumption and the various levels of alcohol intake or abstinence over a period of up to four weeks.

The blood-sample collection method can be advantageous during these tests as solicitor’s can reassure their clients who are afraid of needles, who may otherwise miss collection appointments due to anxiety.

The venipuncture sample collection method can also be used for non-invasive prenatal testing, as analysis of the baby’s DNA can be provided from a sample of the mother’s blood. For more information on prenatal testing please click here.

LFT and CDT testing

LFT

A Liver function test (LFT) measures various enzymes in the blood made by the liver and an abnormal result indicates a problem with the liver. This could be from an elevated Aspartate Aminotransferase (AST) value for example, which is a biochemical indicator of possible alcohol abuse.

We test for a number of enzymes that can indicate abnormality in the liver. These including Bilirubin, AST, ACT, ALP and Gamma GT to ensure the results are as accurate as possible.

There are a number of uses for LFTs, usually for medically related purposes, but AlphaBiolabs can use this test to establish whether a person has drunk to excess over the course of four weeks.

When alcohol is consumed it is absorbed from the stomach and intestines into the bloodstream and is transported to the liver where toxins can be processed and removed. The liver is the first organ that all the blood from the stomach and intestines enters before circulating through the rest of the body. So the highest concentration of alcohol will be in the blood flowing through the liver making it more prone to its damaging effects.

CDT

CDT stands for Carbohydrate Deficient Transferrin. Transferrin is a protein that transports iron around the body. The percentage of carbohydrate molecules that are bound to Transferrin can indicate the levels of alcohol consumption of the individual tested during analysis. Consumption of alcohol can elevate the levels of transferring that are missing the carbohydrate molecule. A greater percentage of transferring that is carbohydrate deficient indicates a greater level of alcohol has been consumed over period of up to 4 weeks.

Can You Cheat an LFT / CDT test?

As opposed to some other forms of alcohol testing, such as urine testing, it is much less likely for false results to be a possibility. False positives for a CDT may occur in the presence of medical complications such as primary biliary cirrhosis, hepatocellular carcinoma and viral liver cirrhosis. Also, an LFT test may be less reliable for alcohol testing purposes when a person’s tolerance for alcohol is extremely high.

Their liver may have adapted to deal with consistent excessive consumption so the test results may appear normal when analysing the enzymes within the liver. For these reasons it is often best for both of these tests to be conducted in parallel and/or with a hair alcohol test for a more comprehensive history of alcohol misuse.

Our sample collection team is also fully qualified to perform hair testing if required, so samples for both blood tests and hair tests can be collected in the same visit if required.
