If a laboratory test results in a negative reading after being diluted twice, it may indicate insufficient sample concentration. Diluting a sample involves adding a solvent or diluent to reduce its concentration. A negative result with double-dilution suggests that the initial sample had low levels of the target substance or analyte, making it difficult to detect. Further dilutions or an alternative testing method may be required for accurate detection.
