Blood Collection Tube ESR Tube
Short Description:
The erythrocyte sedimentation tube is used for the determination of erythrocyte sedimentation rate, containing 3.2% sodium citrate solution for anticoagulation, and the ratio of anticoagulant to blood is 1:4. Slender erythrocyte sedimentation tube (glass) with erythrocyte sedimentation rack or automatic erythrocyte sedimentation instrument, 75mm plastic tube with Wilhelminian erythrocyte sedimentation tube for detection.
Blood Collection / Transport Containers
Frozen Serum: When frozen serum is required, place the plastic transport tubes,immediately in the freezer compartment of the refrigerator. At the time of specimen pickup, inform your professional service representative that you have a frozen specimen to be picked up. A frozen specimen should be held in a freezer at 0°C to -20°C unless a specific test requires the specimen to be frozen at -70°C (dry ice).
1. If you have after-hours pickup for frozen specimens, label the tube with a permanent marker. (Water-soluble markers may wash off with freezing and transport.) Place the tubes in a designated freezer. Prepare the silver gel packs that fit into the Frozen Specimen Keeper by making sure that they also are frozen. As late as possible before the lockbox is to be put out, place the frozen transport tube in the Frozen Specimen Keeper between the silver frozen gel packs. These containers can keep frozen specimens frozen, but they will not be able to freeze specimens at room temperature or refrigerated specimens.
2. Put the Frozen Specimen Keeper containing the specimens in your lockbox according to the pictorial instructions provided (see link above). Your professional services representative will transfer the transport tube from the Frozen Specimen Keeper to dry ice for transport. The Frozen Specimen Keeper will be left in your lockbox for reuse. Specimens for multiple tests should be frozen into different transport tubes.
Note: Some lock boxes may be too small to hold the Frozen Specimen Keeper. The original Transpak containers can be used for these lock boxes.
Frozen Gel Packs:To ensure specimen integrity during warm weather.
Gel-barrier Tubes:Gel-barrier (mottled red/gray, gold, or cherry red-top) tubes contain clot activator and gel for separating serum from cells but include no anticoagulant. Adhere to the following steps when using a gel-barrier tube. Do not use gel-barrier tubes to submit specimens for therapeutic drug monitoring, direct Coombs', blood group, and blood types. There are other times when gel-barrier tubes should not be used.
