Platinum, Serum
Use
This test is used to measure the total serum platinum concentrations in patients who have been administered platinum-based chemotherapeutics. Monitoring the platinum levels in the serum is critical for assessing the patient’s response and adjusting the dosage to ensure efficacy while minimizing toxicity. The test helps in understanding the pharmacokinetics and ensuring treatment is within the therapeutic range.
Special Instructions
Specimens cannot be shared between multiple orders; one specimen per order is required. Use an acid washed or trace metal-free container for sending the serum. Do not use serum gel tubes.
Limitations
The test has not been cleared or approved by the U.S. Food and Drug Administration, which indicates its usage is based on performance characteristics determined by the performing laboratory, NMS Labs. Interference with testing results can occur if the specimen is collected in polymer gel separation tubes, leading to erroneous readings.
