“…Recommendations listed under 3.1-3.8 are grade 2C recommendations (weak recommendation, low quality evidence). We were unable to find any firm evidence besides manufacturer's recommendations, one study in humans and one veterinary study [36,37] to support the above listed recommendation.…”

“…Environmental factors such as temperature, humidity, altitude and light exposure can have a significant impact on the quality of the blood collection equipment. Pre-evacuated blood collection tubes which are beyond the expiry date have a decreased vacuum which may lead to drawing a less than optimal volume of blood and lead to an improper blood to additive ratio [36,37]. Moreover, expired tubes may suffer from some chemical deterioration of the tube additive.…”

Introduction Scope of the guidance Disclaimer Methodology I. Pre-sampling General considerations on appropriate mode of communication with the patient Patient position Step 1. Patient identification (1C) Step 2. Verify patient is fasting and properly prepared (1B) Step 3. Obtain supplies required for venous blood collection (2C) Step 4. Labeling and/or identifying tubes (1C) II. Sampling Step 5. Put on gloves (1C) Step 6. Apply tourniquet (1A) Step 7. Select venepuncture site (1B) Step 8. Clean sampling site (1B) Step 9. Puncture the vein (1A) Step 10. Drawing blood into the first tube (1A) Step 11. Release the tourniquet (1A) Step 12. Gently invert the tubes once immediately after collection (1B) Step 13. Draw additional tubes following the recommended order of draw (1B) Step 14. Remove the needle from the vein and ensure the safety mechanism is activated (1A) Step 15. Dispose of the needle (1A) Step 16. Bandage the puncture site (1C) Step 17. Tell the patient to apply gentle pressure and do not bend the arm (1C) Step 18. Invert all tubes at least 4 more times (1B) Step 19. Remove gloves (1A) III. Post sampling Step 20. Advise the patient to rest for 5 min (1B) IV. Implementation of the guidelines Potential barriers and challenges Framework for a successful implementation of this recommendation Conclusions References

“…Prothrombin time may drop down because of lower concentration of fibrinogen; aPTT may lengthen or shorten depending which process prevails: decrease of fibrinogen or activation of coagulation. Haemolysis may distort other coagulation tests results, for instance decrease of antithrombin level [19].…”

“…Coagulation laboratory must regular review how to improve preanalytics in medical institution. Bostic et al [19] studied, how possible to reduce quantity-not-sufficient specimens (QNS) via several methods and to measure effect of expired collection tubes on the amount of blood that can be drawn. During study period the rate of QNS specimens dropped from 0.7 to 0.3%.…”

Main clinical and scientific aspects of methodology how to choose the right sample for testing to be involved in Plasma for Laboratory Diagnostics chapter as plasma is in use sufficiently widely. Different approach by clinical and research laboratories formed the necessity to discuss the basic laboratory terms and conditions to obtain correct results. Evaluation of preanalytical variables with impact on handling, processing and storage of samples with subsequent meaning for laboratory test results should be known by physicians, biomedical scientists, laboratory technicians and so on. The impact of chemical additives for diagnostics tools, the differences between plasma and serum samples for different laboratory tests and the subsequent analysis, management and traceability of specimens with standardisation value should be taken into account.
