The Risks of Blood Tests: Infection:

Control of infections is significant, and doctors and nurses who take blood must follow strict regulations on the disposal and storage of needles and blood samples.

In rare cases, it is found the site where the needle was passed into the vein has become infected; the wound may become red and swollen.

Excessive bleeding:

After the blood sample has been taken, site of the test often bleed. however, after placing on the wound a cotton pad or a gauze patch, this should stop fairly quickly. In rare cases, the wound can bleed overblown; if so, the health care professional will try to stop blood flow as soon as possible.

Bruising:

Mild blood bruising around the area of the needle is relatively common after a blood test. Severe bruises are usually caused by a failure to press the wound site after the needle is removed (the application of a cotton wool pad to the wound helps stop bleeding, reducing the risk of bruising)  It can also be caused by damage to the vein when the needle was inserted.

Haematoma:

A haematoma is a blood collection under the skin that resembles bruising and causes a solid lump due to the blood clotting. Applying ice packs can help to ease swelling.

Blood test alone cannot diagnose many illnesses and medical problems. Blood tests show whether your blood levels fall within the normal range of different substances. The blood test can also help to identify possible issues early if treatments or lifestyle changes work best
