What This Test Measures

This test includes measurements of enzymes that are produced by liver cells. Bromocresol green and bromocresol purple are used as indicators to assess the functional capacity of liver enzymes, often reflecting overall liver metabolic activity. These tests may also indirectly evaluate bile flow and liver cell health.

Why It’s Ordered

Your healthcare provider may order this test if you have symptoms like fatigue, jaundice (yellowing of skin/eyes), abdominal pain, or unexplained nausea/vomiting. It may also be part of routine check-ups for individuals at higher risk of liver conditions, such as those with a history of alcohol use, hepatitis, or certain medications.

Common Causes of Abnormal Results

Elevated results could indicate liver damage from conditions like hepatitis, cirrhosis, fatty liver disease, or exposure to toxins. Mild elevations might also occur with certain medications, infections, or metabolic disorders.

What to Expect Before the Test

No special preparation is needed. You may fast for 8–12 hours before the test if instructed, but always follow your provider’s specific instructions. Bring any medications or supplements you’re taking.

Clinical interpretation
