What test go in a lavender tube?
EDTA
Lavender top tube – EDTA EDTA is the anticoagulant used for most hematology procedures. Its primary use is for the CBC and individual components of the CBC. The larger 6 mL tube is used for blood bank procedures.
How many times do you invert a lavender tube?
Lavender top tubes must be adequately filled to ensure the correct blood to anticoagulant ratio. Gently invert the tube 8 to 10 times immediately after collection to ensure proper mixing with the anticoagulant.
What is the correct order of draw for multiple tubes?
The draw order for specimen tubes is as follows: Blue tube for coagulation (Sodium Citrate) Red No Gel. Gold SST (Plain tube w/gel and clot activator additive) Green and Dark Green (Heparin, with and without gel)
How full does a lavender-top tube need to be?
Tubes must be completely filled and well mixed. The 4-mL lavender-top (EDTA) tubes must be at least half full with 2 mL of whole blood; the 2-mL pediatric lavender-top (EDTA) tubes must contain a minimum of 1 mL of whole blood.
How much blood do you need in a lavender tube?
Minimum Blood Collection Requirements for Selected Tests
| LAB TEST | COLLECTION DEVICE | AMOUNT ** (CC) WHOLE BLOOD |
|---|---|---|
| Lead | Lavender cap | 0.5 microtainer 1.0 standard tube |
| Magnesium | Light green cap with gel or Gold cap with gel | 0.6 |
| Osmolality, Plasma | Light green cap with gel | 0.7 |
| Osmolality, Serum | Gold cap with gel | 0.7 |
How long is a lavender tube good for?
Specimen stability: DIFF: Refrigerated: 72 hours. Room temperature: 24 hours.
What happens if the order of draw is not followed?
In the era of lyophilized anticoagulants, order of draw is no longer important. Contamination of serum samples with K EDTA will occur routinely if order of draw is not followed. During syringe collections, contamination with K EDTA may rarely occur if order of draw is not followed.
