Zinc Protoporphyrin (ZPP) (948)

What Does the Zinc Protoporphyrin Test Measure?

The ZPP test measures zinc protoporphyrin or ZPP, a substance formed when heme is produced. Heme is the precursor to hemoglobin – a significant part of the red blood cell (RBC) that transport oxygen in the body.

Zinc protoporphyrin is typically found in small amounts in the blood. However, its concentration increases with high exposure to lead and when serum iron is insufficient. Thus, a ZPP blood test often becomes part of an immediate medical intervention against lead poisoning or regular work hazard monitoring. Also, it goes hand-in-hand with a lead blood test.

Among children and pregnant women, it’s often used to help screen for iron deficiency anemia together with other tests, such as the TIBC blood testanemia profile blood test, and a comprehensive iron profile test.

Who Should Take a Zinc Protoporphyrin Blood Test?

People who work closely with lead (manufacturing, construction, and related industries) should consider getting tested to measure their exposure to the element. More so if the following symptoms of lead poisoning are observed.

Furthermore, take a ZPP test if you experience signs and symptoms of iron deficiency anemia, which include:

  • Pale skin
  • Chest pain
  • Brittle nails
  • Sore tongue
  • Irregular heartbeat
  • Shortness of breath
  • Cold hands and feet
  • Headaches and dizziness
  • Extreme fatigue and weakness
  • Unusual cravings for inedible items
  • Loss of appetite (infant and children)

ZPP Blood Test Preparation

No special preparation is necessary before the blood sample collection.

ZPP Lab Test Results

Test values that exceed 35 micrograms per deciliter (mcg/dL) suggest high levels of lead, which prevents heme production. Below this figure, ZPP levels are considered normal. However, the reference range may vary slightly depending on the laboratory. Therefore, it’s best to check the assigned reference interval for accurate comparison.
