Serum or Plasma Mass Concentration of Metabolites Related to Porphyrin Synthesis (e.g., delta-Aminolevulinic Acid, ALA)
This test measures certain chemicals produced during the body’s natural breakdown of heme, a component of red blood cells. It helps assess how well your liver and bone marrow are functioning in producing healthy red blood cells.

What This Test Measures
The test detects specific metabolites involved in heme synthesis, such as delta-aminolevulinic acid (ALA) and coproporphyrin. These substances are intermediates in the process that turns iron into the protein heme, which is essential for red blood cells. Abnormal levels may indicate issues like anemia, liver disease, or certain genetic disorders.
When You Might Need This Test
Your doctor may order this test if you have symptoms like fatigue, weakness, pale skin, or unexplained anemia. It’s also used in monitoring conditions like porphyria (a rare inherited disorder affecting heme production) or during treatment for conditions like lead poisoning, which can disrupt these metabolic pathways.
How the Test Works
A blood sample is taken and analyzed using advanced laboratory techniques, likely high-performance liquid chromatography (HPLC) or similar methods, to measure the concentration of specific metabolites in serum or plasma.
Common Conditions This Test Helps Identify
Elevated or low levels of these metabolites can signal problems such as anemia (especially megaloblastic or sideroblastic types), liver disease, or inherited metabolic disorders like acute intermittent porphyria. It may also be used to monitor treatment responses or detect early signs of metabolic imbalances.
Reference range
Adult males: 4.2-5.9; Females: 3.8-5.1 x 10^12/LN/A
No special preparation required. Stay well hydrated.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is primarily used to diagnose or monitor conditions affecting red blood cell production or heme metabolism. It’s not a routine screening test but is critical for patients with suspected porphyria, liver disease, or those undergoing treatments that could impact these pathways.
