Yellow top tube is used for collecting blood for blood culture (SPS) tests. It is sterile.
A lavender-top tube should be collected for a complete blood count (CBC).
Creatine phosphokinase (CPK) is typically collected in a red-top tube for serum or a green-top tube for plasma.
The haptoglobin test is typically collected in a red-top tube, which does not contain any additives. Alternatively, it can also be collected in a serum separator tube (SST).
The tube for troponin is typically a red-top tube.
Theophylline should be collected in a green-top tube containing lithium heparin.
A lavender-top tube should be collected for a complete blood count (CBC).
Creatine phosphokinase (CPK) is typically collected in a red-top tube for serum or a green-top tube for plasma.
LFT (Liver Function Test) should be collected in a red or gold/yellow test tube, which signifies a tube containing a gel separator and clot activator. Red and gold/yellow are the commonly used colors for tubes that contain clot activator and gel separator for serum separation.
The haptoglobin test is typically collected in a red-top tube, which does not contain any additives. Alternatively, it can also be collected in a serum separator tube (SST).
Blood for CBC is usually collected in a purple-top tube (containing EDTA).
The tube for troponin is typically a red-top tube.
Theophylline should be collected in a green-top tube containing lithium heparin.
It is called serum-separator-tube (SST) and it is dark yellow (just so there's no confusion there are two yellow tops when it comes to blood draws and the orders each go in and that is light yellow and dark yellow).

A PSA test is typically collected in a lavender-top tube, which contains the anticoagulant EDTA.
EBV (Epstein-Barr virus) is typically collected in a lavender or purple top tube for hematologic testing.
For titers, blood can be collected in a red-top tube (serum separator tube) or a gold-top tube (serum separator tube with gel). The serum is then separated from the blood cells by centrifugation and used for the titer test.
