Dengue IgG/IgM antibodies

The direct bilirubin test is an essential diagnostic procedure used to evaluate liver function by measuring the amount of conjugated bilirubin in the blood or urine. Bilirubin, a yellow pigment, is produced during the breakdown of red blood cells and is processed by the liver to become water-soluble for excretion. This test is crucial for diagnosing liver and bile duct disorders, such as hepatitis, cirrhosis, and bile duct obstructions, where the liver's ability to conjugate bilirubin is compromised. The test specifically measures the conjugated form of bilirubin, distinct from the unconjugated form, and is performed by analyzing a blood sample. Results are expressed in milligrams per deciliter, with normal levels ranging from 0 to 0.3 mg/dL. Elevated levels may indicate liver diseases, bile duct obstructions, or rare liver conditions. The direct bilirubin test is often part of a comprehensive liver panel, providing valuable insights for diagnosing and managing liver-related health issues.

Purpose of the test

The direct bilirubin test is essential for evaluating liver function and diagnosing liver and bile duct disorders. It measures conjugated bilirubin, processed by the liver for excretion. Elevated levels can indicate:

- Liver diseases: hepatitis, cirrhosis
- Bile duct obstructions: gallstones, tumors
- Cholestatic drug reactions
- Rare syndromes: Dubin-Johnson, Rotor

Symptoms of elevated bilirubin include jaundice, dark urine, and abdominal pain. The test uses serum or plasma, with results typically available within a day. Proper specimen handling is crucial to avoid rejection.

Who Should Get Tested

In regions where dengue fever is endemic, testing for Dengue IgG and IgM antibodies is essential. This test helps identify past or current infections and distinguishes between primary and secondary infections, which can have different clinical outcomes.

- IgG Antibodies: Indicate past exposure; persist long-term.
- IgM Antibodies: Indicate recent infection; appear early.

Testing involves collecting acute and convalescent sera to compare antibody levels. This helps determine infection type. Specimens must be handled carefully to ensure accuracy. ELISA is used for detection, but cross-reactivity with other flaviviruses can occur.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results is essential for interpreting the direct bilirubin test, a key diagnostic tool for liver function. This test measures conjugated bilirubin, processed by the liver for excretion. Elevated levels can indicate:

- Liver diseases: Hepatitis, cirrhosis
- Bile duct obstructions: Gallstones, tumors
- Drug reactions: Affecting bile flow

Symptoms of elevated bilirubin include jaundice and dark urine. The test is part of a liver panel, requiring serum or plasma, with results typically available within a day. Proper specimen handling ensures accurate results.
