The problem with counting
A weekly count is a snapshot. Between counts, stock moves with every test, every wasted vial and every borrowed box. By the time a count reveals a shortage, a result may already be late.
How test-based deduction works
Each test type has a recipe: the reagents and quantities it consumes. When a technician logs a test, the system deducts that recipe from stock automatically. Because the recipe is defined once, every technician deducts the same amounts.
Handling the exceptions
Real benches have exceptions: a spilled vial, a repeat run, an urgent off-system use. A good system lets you record these as explicit adjustments with a reason, so waste is visible rather than hidden in the count.
What it unlocks
Once consumption is captured from tests, the system can forecast stockouts from actual usage, suggest reorders, and show cost per test. None of that is possible from counts alone.
Common questions
Yes. Periodic counts verify the system and catch loss or breakage. With test-based deduction they confirm accuracy instead of establishing it.
The recipe sets the standard amount. Variations are recorded as adjustments, which makes them visible and reviewable.
