Can CBC be on citrate tube?
To report CBC data from a citrate tube only, apply the 1.1 correction factor to all parameters reported per unit volume, which includes the red blood cell count, WBC count, platelet count, hemoglobin, and absolute counts for all cell types in the WBC differential.
What tube do you use for CBC with diff?
Specimen required: EDTA lavender-top tube or microcollection tube.
What is sodium citrate tube used for?
The “citrate tube” is for collecting blood for performing coagulation studies. It contains 3.2% sodium citrate as its anticoagulant. [3] Mixing the blood inside the tube a few times is also recommended to form the plasma. There is no anticoagulant or additive inside the tube.
What is citrate platelet count?
A Citrated Platelet Count will be suggested by Haematology when clumped platelets have been seen on a blood film on one or more occasions, significantly lowering the platelet count. When this occurs the platelet count will be removed from the FBC report and a comment added.
What happens if you Centrifuge a CBC?
If specimen is centrifuged before clotting is complete, a fibrin clot will form on top of the cell. This finding is frequent in hemolyzed specimens. Also, the gel barrier may not be intact and could cause improper separation of serum and cells, possibly affecting test results.
What happens if you underfill a tube with blood?
If tubes are underfilled, the blood:anticoagulant ratio may result in hemolysis. Avoid underfilling tubes by having an ample supply of tubes of various capacities.
What tubes for CBC and CMP?
Green Tube/Plasma: Centrifuge after collection. Gold Tube/Serum: Allow blood to clot for 30 minutes in a vertical position and centrifuge within 2 hours.
What tubes do you use for blood tests?

What tube is used for hematology?
EDTA
In general, hematology testing is performed on EDTA- (purple top tube) anticoagulated blood.
What is a citrate blood test?
Sodium Citrate (Light Blue) For coagulation and platelet function tests. Like EDTA, citrate acts by removing calcium from the blood. Unlike EDTA, it’s reversible—so calcium can be added back to study coagulation under controlled conditions. Citrated plasma is also used to measure coagulation-relevant factors.
Is citrate an anticoagulant?
Citrate is essentially a regional extracorporeal anticoagulant, with a short systemic half-life of around 5 min, metabolized predominantly by mitochondria in the liver, skeletal muscle and the kidney.
What tubes are used for CBC?
Additive: anticoagulant SPS (Sodium Polyanetholsulfonate)&ACD (acid citrate dextrose)
