Why It Is Done. A phenylketonuria (PKU) screening test is done to see whether a newborn baby has the enzyme needed to use phenylalanine in his or her body. If this test shows that your baby has a phenylalanine problem, the doctor will do further testing to check whether your baby has PKU.he blood sample for PKU is usually taken from your baby's heel (called a heel stick). The test is done in the first few days after birth, as early as 24 hours after birth.
Add image to my collection. Technology to inject drugs into the body is a recent development. Hypodermic syringes (hypodermic means âbeneath the skinâ) consist of a hollow needle attached to a syringe. They pierce the skin and inject substances into the bloodstream. They are also used to extract liquid such as blood from the body.
See guidelines on page 3. The aim is to transfer the needle/syringe into an appropriate container safely to minimise the risk of needle-stick injury. A sharps container is a receptacle intended for the collection and disposal of sharps.njection of blood-borne viruses is the major hazard of needle stick injuries, especially the viruses that cause AIDS (the HIV virus), hepatitis B and hepatitis C. The term âsharpsâ means objects or devices with sharp points, protuberances or cutting edges that are capable of cutting or piercing the skin.
