Today's quick tip
Custom Visuals
Blood collection at a glance
These illustrations are built directly into the page and require no image hosting.
Blood Collection Tubes
Tube color is a quick visual clue. Always verify the additive and current receiving-laboratory requirements.
Order of Draw
Gentle Tube Inversion
These visuals are teaching aids. Do not rely on a generic inversion count, tube example, or order when the current laboratory directory or manufacturer instructions specify something different.
Venous Collection
General order of draw
Use this sequence as a quick reference for routine venous collection.
Do not apply the venous order of draw to capillary tubes. Follow the current capillary-collection system instructions.
Searchable Library
Tube colors and common examples
Open a card for additives, specimen type, common test examples, and handling reminders.
Try a tube color, additive, specimen type, or common test name.
Specimen Integrity
Collection hard stops
These standards matter more than memorizing a color.
Use full name and date of birth and match the specimen to the active order.
Label in the patient’s presence. Never place an unlabeled specimen aside for later.
Underfilling additive tubes can change the blood-to-additive ratio and may cause rejection.
Invert additive tubes as directed. Do not shake vigorously.
