Light Blue.
The additive in these tubes is usually Na+ Citrate and there is a marking on the test tube to indicate the minimum fill. Blood must come at least up to the line or it will not be acceptable.
A lavender/purple-top tube is commonly used for calcium testing.
You would typically use a lavender-top tube for transferrin saturation testing. This tube contains the anticoagulant EDTA, which is suitable for testing iron-related parameters like transferrin saturation.
A lavender/pink tube is typically used for potassium (K+) testing. It contains the anticoagulant EDTA to preserve the sample for accurate testing.
You could use a Red/Gray SST tube, or you could use a Green sodium heparin tube.
No, heparin tubes are not typically used for prostate-specific antigen (PSA) testing. The recommended tube for PSA testing is a serum separator tube (SST) or a plain red-top tube to obtain a serum sample for analysis.

No, heparin tubes are not typically used for prostate-specific antigen (PSA) testing. The recommended tube for PSA testing is a serum separator tube (SST) or a plain red-top tube to obtain a serum sample for analysis.
The tube color commonly used for collecting blood for electrolyte testing is a green-top tube, which contains lithium heparin as an anticoagulant. The green-top tube helps preserve the integrity of the sample for accurate electrolyte measurements.
A gold or red/gray tiger top tube (serum separator tube) is typically used for GGT (gamma-glutamyl transferase) testing. This tube contains a clot activator and gel separator to obtain serum for testing.
A PKU is a serum test, so it goes in a red top.
A lavender or purple-topped tube is typically used for collecting a sample for HIV testing.
A lavender-capped tube (EDTA tube) is typically used to collect blood for antinuclear antibody (ANA) testing. The EDTA helps prevent clotting and preserves the sample for testing.
