Blood test – Early detection and diagnosis

Blood test - what is involved?

A blood test is defined as the extraction of a small amount of (approx. 2 - 50 ml) venous or arterial blood, which can be examined with regard to its contents and solid particles using different laboratory medicine methods. The result is a diagnostically relevant blood count, which provides an indication of the medical condition and diseases or risks of disease.

Blood test – when?

There are several application possibilities for blood samples and they are becoming increasingly sophisticated. One single blood sample can provide up to 40 different pieces of information on the medical condition of a patient. Therefore, blood tests are standard for almost all preventive medical check-ups, and blood counts are a fixed component of the general clinical examinations for pre-operative preparations, inflammations, tumours, infections, coagulation disorders, anaemia and blood diseases.

Blood test – how?

Blood samples can be taken from both arteries and veins. Venous blood is used for the majority of examinations; however, arterial or capillary blood samples may be necessary for individual examinations.
Venous blood samples are normally taken from the inside of the patient’s elbow, who should be sat or lying down at the time. In order to make the vein more visible, the blood flow is constricted for a short period of time at the upper arm by means of a tourniquet or a cuff. The puncture site is cleaned with a disinfectant. The vein is punctured through the skin with a needle and the amount of blood required is extracted with a syringe or a vacuum blood collection tube. A gauze pad or plaster is pressed onto the puncture site for around 60 seconds, so that the bleeding stops. For this purpose, the elbow should not be bent, so that the vein is not reopened and a bruise is not caused.

Blood test – are there alternatives?

Blood tests are painless and without risk. And there is no alternative. If only very small amounts of blood are required, e.g. blood glucose level, then the fingertip or the earlobe can be pierced with a small lancet and a few drops of blood can then be squeezed out.
