  • Fetal blood testing

    Fetal blood testing

    Fetal blood testing is performed during labor to test the blood pH of the baby which can determine its well-being during delivery. A small puncture is made in the scalp and fetal blood droplets are collected in a thin glass tube. Testing the scalp pH can help your doctor decide if your fetus is getting enough oxygen during labor. This helps determine if your baby is healthy enough to continue labor, or if a forceps delivery or cesarean delivery might be the best route of birth.

  • Newborn screening testing

    Newborn screening testing

    Blood is routinely drawn from newborn infants for testing. Blood is obtained by a heel stick and collected on a special blotter paper. Routine testing usually includes phenylketonuria, thyroid function, hemoglobin S (sickle cell disease), and may test for other disorders. Newborn screening programs vary from state to state. Testing can be tailored to the local population, determining what routine testing should be done.

  • Lung diffusion testing

    Lung diffusion testing

    Lung diffusion testing measures how well oxygen passes from the air sacs in the lungs into the blood.

  • Lead testing

    Lead testing

    Lead is a natural element with thousands of uses. Because it is widespread (and often hidden) lead can easily contaminate food and water where it is undetectable to the eye or taste.

    Skin testing - PPD (R arm) and Candida (L)

    The right arm represents a positive reaction to PPD (a skin test for tuberculosis protein). The left arm represents a positive reaction to Candida protein. Candida antigen is tested to determine if the individual's immune system is functioning well; a normal immune system demonstrates a positive reaction.
