Blood tests that require warming include those for therapeutic drug monitoring, such as certain assays for lithium and some enzymes. Tests that need chilling are typically those for ammonia, lactate, and certain hormone levels, as they can be affected by temperature. Tests that need to be kept in darkness include those for bilirubin and certain vitamins, as light exposure can degrade these substances. Proper handling of these samples is crucial to ensure accurate test results.
