Yes, aside from lithium heparin tubes, there are several other types of evacuated tubes commonly used in clinical laboratories to obtain blood samples for various laboratory tests. Among these tubes are EDTA (Ethylenediaminetetraacetic acid) Tubes, which contain EDTA as an anticoagulant and are utilized for hematological studies such as complete blood count (CBC), blood typing, and erythrocyte sedimentation rate (ESR) determination. Another commonly used type is Sodium Citrate Tubes, which contain sodium citrate as an anticoagulant and are employed for coagulation studies, including prothrombin time (PT), activated partial thromboplastin time (aPTT), and thrombin time (TT) tests. Additionally, Serum Separator Tubes (SST) are utilized, containing a gel separator and suitable for serum-based tests like biochemical analyses, including liver function tests, lipid profiles, and hormone assays. These various evacuated tubes play a crucial role in facilitating accurate and efficient laboratory testing, ensuring the provision of reliable diagnostic information for patient care.

The assay dictates which tube to use. EDTA and sodium citrate containers contain preservatives that interfere with clinical chemistry assays. Red top clotted serum tubes can be used for any assay a yellow top serum gel tube is used. The only difference is the red top tubes don't contain gel to separate the cells from the serum.

There are tube guides published on the internet.
