SARS-CoV-2 RT PCR

The copper serum or plasma test is a vital diagnostic procedure used to evaluate copper levels in the blood, crucial for identifying copper deficiency or toxicity. This test measures both protein-bound and free copper, aiding in the diagnosis of disorders like Wilson’s disease and Menkes syndrome. A blood sample, collected in a royal blue-top tube, is required, ensuring sample integrity. The test employs quantitative inductively coupled plasma-mass spectrometry (ICP-MS) for precise measurement. Results are interpreted against a normal range of 62 to 140 mcg/dL, with deviations indicating potential health issues. Elevated copper levels may suggest toxicity, infection, or medication effects, while low levels could indicate nutritional deficiencies or kidney disease. The test is often paired with ceruloplasmin tests, 24-hour urine copper tests, and liver copper measurements for comprehensive assessment. Patients should avoid supplements and certain drinks before testing to ensure accuracy. This test is crucial for diagnosing and managing copper-related health conditions.

Purpose of the test

The copper serum or plasma test is vital for assessing blood copper levels, crucial for diagnosing copper imbalance conditions. Key aspects include:

- Purpose: Measures total copper, aiding in diagnosing disorders like Wilson’s disease and Menkes syndrome.
- Specimen Requirements: Blood sample in royal blue-top tubes; processed within 2 hours.
- Methodology: Uses ICP-MS for precise measurement.
- Interpretation: Normal range is 62-140 mcg/dL; deviations indicate potential health issues.
- Clinical Significance: Essential for managing symptoms from copper imbalance.
- Related Testing: Includes ceruloplasmin and 24-hour urine tests.
- Patient Preparation: Avoid supplements and certain drinks before testing.

Who Should Get Tested

The SARS-CoV-2 RT-PCR test is crucial for detecting COVID-19. It identifies viral RNA in respiratory specimens, such as nasopharyngeal swabs. Key steps include:

- Sample Collection: Obtain respiratory specimens.
- Nucleic Acid Extraction: Process specimens to extract RNA.
- Reverse Transcription: Convert RNA to cDNA.
- PCR Amplification: Amplify cDNA using specific primers.
- Detection: Measure fluorescence to determine viral load.

This test is vital for diagnosing COVID-19, guiding treatment, and informing public health decisions, despite limitations like potential false negatives.

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 crucial for effective diagnosis and treatment. Here’s a concise guide:

- Normal Range: Copper levels typically range from 62 to 140 mcg/dL.
- Elevated Levels: May indicate copper toxicity, infection, or medication effects. In women, pregnancy and contraceptives can elevate levels.
- Low Levels: Could suggest kidney disease, nutritional deficiency, or absorption issues. Note: Wilson’s disease may show low blood copper despite organ accumulation.
- Further Testing: Additional tests like ceruloplasmin, 24-hour urine, and liver copper measurements may be needed for comprehensive assessment.
