Record the three fields that matter most
Every reconstitution entry should capture the vial label amount, the exact diluent volume added, and the final concentration that results from that pairing.
If those three values are missing or scattered across separate notes, it becomes hard to audit later calculations or compare runs performed by different team members.
- Record total vial content in mg.
- Record diluent added in mL.
- Write the resulting mg/mL and mcg per 0.01 mL reference.
Add a small aliquot reference table below the formula
A short table for common aliquot sizes removes repeated mental math during routine prep. It also reduces transcription mistakes when the same concentration is used across multiple sessions.
- 100 mcg reference
- 250 mcg reference
- 500 mcg reference
- 1,000 mcg reference
Use the table as a verification aid, not as a substitute for reviewing the underlying concentration formula.
Treat the entry as an audit trail
The notebook line should stand on its own. If a different person opens the record later, they should be able to reconstruct the concentration and confirm any aliquot conversion without asking what happened at the bench.
That usually means including the lot, date, and initials beside the concentration record.
