It carries oxygen in the RBC's to other parts of the body giving it oxygen.(Hemoglobin Is Like an Uber Driver Delivering Oxygen To Other Places In The Body).What Is Hematocrit (HCT)? What Does It Measure? Hematocrit is the measure of the ratio of Red Blood Cells (RBC's) to other types of cells in our blood.What Does a Hematocrit (HCT) of 50% Mean?It means that fifty percent or half of the cells in your blood are Red Blood Cells (RBC's). The other half are WBC's, Platelets, etc.What Is The Normal Hemoglobin (HGB) For Males? 14-18 g/dL (Grams Per Deciliter).What Is The Normal Hemoglobin (HGB) For Females? 12-16 g/dL (Grams Per Deciliter).What Hematologic Condition Could A Dramatic Increase In Hemoglobin (HGB) Be The Result Of?Polycythemia Vera.This is a condition when the plasma of the blood becomes packed with RBC's and becomes very thick and viscous.What Fluid Condition Could Cause A Dramatic Hematocrit (HCT) Elevation?Dehydration. If the patient is too dehydrated say from excessive N/V or excessive sweating (diaphoresis), the blood will become very concentrated and thick.Note, this does not mean that the RBC's have elevated like in polycythemia vera, it just means that the RBC's have become more concentrated due to the lack fluid thus increasing Hematocrit (HCT) Levels.

What Is a Normal Hematocrit (HCT) For Males? 42-52%.What Is A Normal Hematocrit (HCT) For Females? 37-47%.Numerically, What Is A Good Way To Remember Hemoglobin (HBG) Ranges?Depending on the gender, its always 4 or more.Females 12-16 g/dL.Males 14-18 g/dL.Numerically, What Is a Good Way To Remember Hematocrit (HCT) Ranges?Depending on the gender, it's always 10% or more.Females 37%-47% Males 42%-52% What Hematologic Condition Could Be A Cause of Abnormally Low Hematocrit (HCT) and Abnormally Low Hemoglobin (HGB)?Anemia.What Physical Event Could Be The Cause of Abnormally Low Hematocrit (HCT) and Abnormally Low Hemoglobin

(HGB)?

Hemorrhage or some sort of other excessive blood loss.What Is The Normal White Blood Cell (WBC) Count? 5,000 - 10,000/mm3 (cubic millimeter).What Could Abnormally High WBC Levels Indicate? An infection occurring in the body.What Could Abnormally Low White Blood Cells (WBC's) Indicate?Immunosuppression. Possibly due to chemotherapy, or transplant immunity suppression drugs.What Are The Normal Levels For Platelets?150,000 - 400,000 mcL (Per Microliter).What Could Potentially Occur With a Low Platelet Level? Excessive Bleeding.What Could Potentially Occur With A High Platelet Level? Excessive clotting -- the clots may even mobilize and become a pulmonary embolus (PE).Which Anticoagulant Works With The Activated Partial Prothrombin Time (aPTT) Heparin (Lovenox).What Is The Normal Partial Prothrombin Time For Someone Who IS NOT On Anticoagulants?20-30 Seconds.What Do We Want The Activated Partial Prothrombin Time (aPTT) To Be When The Patient Is On Anticoagulants?

1.5 - 2.5x longer than the average.

What Do We Want Your (aPTT) To Be If Your PTT Is Usually 20 Seconds?30 - 45 seconds.20 x 1.5 = 30.30 x 2.5 = 45.What Do We Want Your (aPTT) To Be If Your PTT Is Usually 30 seconds?45 - 75 seconds.30 x 1.5 is 45.30 x 2.5 is 75.What Does It Mean If Your PTT is Below 20 Seconds? It means your blood is clotting very quickly. It taking very little time for your blood to form clots intrinsically.What Does It Mean If Your PTT is Above 30 Seconds? It means you blood is clotting very slowly. It's taking quite a long time for your blood to form clots intrinsically.Does The PTT Test The Intrinsic or the Extrinsic Pathway? The Intrinsic Pathway.All this means is that the PTT test is testing how fast or slow a clot forms due to internal trauma of the blood vessels.The intrinsic pathway is faster form a clot.

between-intrinsic-and-extrinsic-pathways-in-blood-clotting/ Does The PT (Prothrombin Time) Test the Intrinsic Or The Extrinsic Pathway?The Extrinsic Pathway.All this means is that the PT (Prothrombin Time) test is testing for how fast a clot forms due to external trauma of the surface of the body.The extrinsic pathway is slower to form a clot.

You can read more about this at this website https://pediaa.com/difference-

between-intrinsic-and-extrinsic-pathways-in-blood-clotting/ What Is The Normal Extrinsic PT (Prothrombin Time) Time? 10 - 12 seconds.What Does It Mean If Your PT (Prothrombin Time) Is above 12 Seconds?It's taking your blood longer than normal to form a clot extrinsically.What Does It Mean If Your PT (Prothrombin Time) Is Below 10 Seconds?It's taking your blood shorter than normal to form a clot extrinsically.What Is "INR" and What Medication Is It Associated With?INR stands for the international normalized ratio -- it is based off your PT (Prothrombin Time) and it measures how well warfarin is working in the slowing down of clots.

What Are The Normal INR Ratios When A Patient IS NOT

ON ANTICOAGULANTS?

0.9 - 1.2.

This means that without warfarin, your INR should be 0.9-1.2.What Is the Therapeutic INR Ratio? 2-3.Therapeutic INR ratio refers to your clotting while taking warfarin. Warfarin slows the clotting time, so you your therapeutic INR needs to be greater than 0.9 - 1.2.When Referring To Coagulation Panels, What Does A Higher Number Generally Indicate?A longer amount of time for the blood to form a clot.Greater risk for bleeding.When Referring To Coagulation Panels. What Does A Lower Number Generally Indicate?A shorter amount of time for the blood to form a clot.Lower risk of bleeding, but greater risk for excessive clotting.What Is The "Heparin Monitoring Memory Trick?" A trick used to remember that Heparin affects "PTT" or Partial Thromboplastin Times.A pair of hands have 10 fingers; the word Heparin has 7 letters which would take up 7 fingers on the pair of hands.There would only be 3 fingers left, and the abbreviation "PTT" with its 3 letters would take up the remaining three fingers on the remaining hand.What Is The "Warfarin Monitoring Memory Trick?" A trick used to remember that Warfarin affects the "PT" or Prothrombin Times.A pair of hands have 10 fingers. The word "Warfarin" has 8 letters which would take up 8 fingers on the pair of hands leaving two fingers left.The remaining two fingers would be associated with the two letter abbreviation "PT" for Prothrombin time.What Is The Difference Between "PTT," and "aPTT." "aPTT," or "Activated Partial Thromboplastin Times" is simply when the patient has begun the usage of Heparin, which has "activated" their "PTT" thus making it "aPTT." This new "aPTT" should have a much longer clot time than regular "PTT."
