I attempt to make the most accurate material I can. However, mistakes happen. Below is a list of mistakes identified in this video.
Known errors in this video:
At 1:34 I state that plasma still contains platelets after centrifugation. This is generally not true. The platelets settle into the thin white "buffy coat" that also contains the white blood cells. You can alter the process to create a platelet rich plasma. I have links below on how that works.

    This was *very* helpful. I breed border collies via AI and with the crazy prices of progesterone tests have decided to do my own draws and send the samples out to university vet lab. My vet tech friends showed me how to do the draw [butterflies much easier than TB tubes]. This told me how to process them before sending them out. I can do my own tests for 1/3 cost of commercial/vet labs, including shipping.

Which of the two methods would produce a more obvious cloudy separation of prp ? thank you in advance ☺️

    Nice video, i am Dr vet trying to refresh after decades doing administrative, a little correction 6:50 platelets are spun down in EDTA tubes to cell portion (they lie between RBC's and the buffy coat and if spun correctly it be none in plasma, the difference in these two show on a quick assessment using field refractometar and it is about 7 percent fibrinogen of total (TP) plus 1 percent coags of total (TP) captured in coagulum so if the total blood protein (TP) human plasma is e.g 7.5 g/dl it will be 6.9 g/dl for the same blood sample using serum.

    Thus, in plasma, when blood is collected for anticoagulant, there will be no platelets under appropriate centrifugation conditions, but there will still be inactive coagulation factors (proteins of the blood coagulation system, including fibrinogen). When collected on a clot, not only platelets clot, but also fibrin from fibrinogen after activation of the coagulation factors, so the serum contains neither platelets nor fibrinogen.

    It all depends on the type of analysis. Sometimes it is ok to sample the serum directly from the tube, but you must be careful not to disrupt the cells or mix the sample. I'm guessing most analyses should be complete in an hour or less.

To what type of tube - or what color cap tube - should the PPP be transfer to for a second spin, and, 2. Would the same speed/time be applied to extract the PRP with the second spin? Thank you!!!

    At 6:50, the anticoagulant tube has plasma "with unused coagulation factors" and platelets. Clot formation inside a tube is caused by fibrinogen turning into fibrin (not platelets) by action of thrombin and initially by the contact with the glass from the tube (silica).

    Ideally you should centrifuge the blood and remove the serum immediately. Then the isolated serum can be stored or frozen for later analysis. Keeping the blood cells in the sample you run the risk of hemolysis.

    I can't say for sure but you can probably hold onto the blood for an hour maybe even 2 hours before centrifuging. If you are attempting to get serum (not plasma) then you need to wait until the blood is coagulated. That usually takes about 10-15 minutes.

  • @VivoPhys

    3 жыл бұрын

    Hi Kimi O. I do not know how much red blood cell in your plasma sample is "too much", but I would assume you are correct that it does not take much. The reason is the contents of the cytosol in the red blood cell is different from the contents of the plasma/serum. So if you get red blood cells into your plasma/serum sample they will likely hemolyze (burst) releasing their content. This can dramatically change the level of some things your attempting to measure like plasma/serum potassium. So you will get an inaccurate result.

    Hi Nɪᴋɪᴛᴀ Rɪᴄᴇ. I do not know the process of testing blood for HIV. However, typically inverting the sample is just to mix the chemicals in the tube with the blood to either promote or inhibit clotting. I cannot imagine that it would cause an error in the test. At worst, it would probably just ruin the blood so it could not be tested at all.

    According to BD's website: "BD Vacutainer Plus plastic serum and SST tubes are coated with silicone and micronized silica particles to accelerate clotting. A silicone coating reduces adherence of red cells to tube walls. The silica coating can sometimes cause the inner tube wall to appear cloudy and/or filmy. This cloudy appearance does not make the tubes unacceptable for use." www.bd.com/en-us/offerings/capabilities/specimen-collection/blood-collection/venous-collection/bd-vacutainer-blood-collection-tubes/vacutainer-blood-collection-tube-faq/general-tubes-faq How exactly the micronized silica particles cause platelet aggregation and clotting is unclear to me but I found this: "It was reported that SiNPs penetrated the platelet plasma membrane and stimulated a rapid and prolonged NO release, IIbIIIa activation, and finally the platelet aggregation [25]." www.hindawi.com/journals/bri/2016/2959414/

    I spent some time looking this up and found a lot of poor explanations out there. Hopefully someone can double check my answer to be sure it is accurate and maybe give a better one. Regardless, here is my best attempt to explain (and understand) this. The centrifuge tube holders apply a horizontal force on the tube to make it move. Because the tube is attached to a circular object that can only spin (assuming it does not break) there is a simultaneously applied force of the tube holder pushing the blood tube towards the center of the centrifuge preventing the tubes from flying away. This force is called centripetal force. Applying these two forces simultaneously causes the tubes to spin instead of moving in a straight horizontal line. Remember that inertia = mass x acceleration (in this situation the blood tube is constantly accelerating from the forces already described or it would not go in a circle). All parts of the blood have a similar acceleration because the whole tube is moving as a unit. Keep in mind the tubes of blood are spinning with the bottom of the tube facing towards the outside of the circle, and blood is liquid (plasma) with blood cells suspended throughout. The components of the blood (e.g. red blood cells) have more mass than the liquid portion (plasma). Going back to the inertia equation, the key difference between the various blood components is there mass not their acceleration. Therefore, the more mass they have the more inertia they have. So as they accelerate towards the center of the centrifuge the components of blood with more mass (more inertia) end up migrating towards the outside of the centrifuge (bottom of the tube). This is because they are more resistant to that acceleration (i.e. more inertia) than the less massive portion of the blood.

    Often, neither doctors or nurses. The person who draws the blood varies between hospitals, and may vary from time to time in the same facility. The blood may be drawn by a certified medical laboratory scientist (MLS, bachelor's degree laboratory professional), a certified medical laboratory technician (MLT, associate's degree medical professional), or a phlebotomist (may be on the job trained, or a certified graduate of a phlebotomy program), or a nurse or physician (limited training in blood collection in nursing or medical school). Centrifuging and separating the blood is done in the laboratory, and again, depending on the facility, the person who does this may be an on the job trained laboratory assistant, may be an MLS or MLT, or a combination. Who does the TESTING of that sample? That will be a college-educated laboratory professional. It may be a certified medical laboratory technician (MLT) with an associate's degree, or a certified Medical Laboratory Scientist (MLS) with a bachelor's degree.
