Quizplus · Accepted Answer

The TdT test, which is used to detect terminal deoxynucleotidyl transferase in cells, requires specific specimen conditions for accurate results. These include using a nonheparinized bone marrow aspirate to prevent anticoagulant interference with the assay, separated marrow cells that are washed with culture media to ensure purity and viability of the cells for testing, and storing slides at 4°C in the dark to preserve the integrity of the samples until analysis.
