The blood movie (commonly referred to as a blood smear) is usually a important a part of clinical testing. When performed, it permits the technologist to view the actual physical appearance of the pink and white blood cells microscopically. The distribution of the cells, in addition to their morphology, may be altered by poor slide preparation.

Immediately centrifuge the specimen for as long as 10 minutes or as specified by the tube producer. Put the Frozen Specimen Keeper containing the specimens in your lockbox in accordance with the pictorial directions provided (see link above). Your professional services representative will transfer the transport tube from the Frozen Specimen Keeper to dry ice for transport.

For some exams, similar to chemistry procedures, fasting samples are often the specimen of selection. Also, as a result of hemolysis interferes with many procedures, please submit samples which might be as free from hemolysis as possible. This section is presented as a guide for educated venipuncture technicians, or phlebotomists, and is not meant to coach individuals in venipuncture method.

All tubes must be labeled with the patient's full name or identification quantity because it seems on the check request kind or affix bar code. Also, print on the label the kind of plasma submitted (eg, “Plasma, Sodium Citrate,” “Plasma, EDTA,” etc). Be certain to offer the laboratory with the amount of plasma specified. Place the tip of the pipette towards the side of the tube, roughly ¼ inch above the cell layer.

Rest the left finish of the spreader at a 45° angle, approximately ½ inch opposite the drop of blood on the slide. This angle prevents the white cells from bunching alongside the sides.

Collect blood into the BD PPT™ following commonplace process for venipuncture and pattern collection. Failure to fill the tube will trigger an improper blood-to-anticoagulant ratio and will yield questionable and/or QNS check outcomes. The BD Vacutainer® Plasma Preparation Tube (PPT™) is a plastic evacuated tube used for the collection of venous blood in order to prepare undiluted plasma for use in molecular diagnostic testing. When frozen plasma is required, place plastic transport tube(s) instantly in the freezer compartment of the fridge, and notify your skilled service consultant that you've got a frozen specimen to be picked up. Label all tubes clearly and thoroughly with all pertinent data or bar code.

The Frozen Specimen Keeper will be left in your lockbox for reuse. Specimens for multiple exams ought to be frozen into different transport tubes. (See Figure 10.) Inspect the serum for signs of hemolysis and turbidity by holding it up to the sunshine. Place the collection tube within the upright position within the rack, and permit the blood to clot at room temperature for 30 to 60 minutes.

If clotting fails to happen inside 60 minutes, notify the physician. There are two necessary tips to comply with when submitting blood specimens.
