Which test requires a specimen with a 9 1 ratio of blood to anticoagulant?
Venous blood specimens for coagulation assays should be collected into a tube containing 3.2% buffered sodium citrate tube (blue top tube), yielding a whole blood sample with a 9:1 blood to anticoagulant ratio.
Which blood specimen should be chilled during a 45 minute transport?

|WHICH BLOOD SPECIMEN SHOULD BE KEPT WARM DURING TRANSPORT TO THE LABORATORY?||COLD AGGLUTININS|
|WHICH ANALYTE IS PHOTOSENSITIVE?||BILIRUBIN|
Which specimen can be centrifuged immediately?
Plasma specimens are obtained using a Vacutainer tube containing an anticoagulant. These specimens can be centrifuged within minutes after collection. Any vacuum tube containing an anticoagulant should be inverted gently 8-10 times immediately after blood collection to ensure the intended action of the additive.
Which blood specimens should be chilled?
1. Certain analytes must be preserved prior to analysis by keeping the specimen chilled. To ensure accurate results of such specimens, transport them in ice slurry. i.e. ACTH, Acetone, Angiostensin Converting Enzyme (ACE), Blood Ammonia, Catecholamines, Free Fatty Acids, Lactic Acid, Pyruvate, Renin Activity.
What POC test can be used to monitor heparin?
activated clotting time (ACT)
Why is aPTT used to monitor heparin?
Laboratory monitoring is widely recommended to measure the anticoagulant effect of unfractionated heparin and to adjust the dose to maintain levels in the target therapeutic range. The most widely used laboratory assay for monitoring unfractionated heparin therapy is the activated partial thromboplastin time (aPTT).
What are the advantages of POCT?
The theoretical advantages of POCT are faster turn-around-times (TAT), more rapid medical decisions, avoidance of sample identification and sample transport problems and the need of only small specimen volumes.
What is a measurement of the percentage of packed RBC in a volume of blood?
Hematocrit (HCT, packed cell volume, PCV). This test measures the amount of space (volume) red blood cells take up in the blood. The value is given as a percentage of red blood cells in a volume of blood. For example, a hematocrit of 38 means that 38% of the blood’s volume is made of red blood cells.
What volume is 1 unit of blood?
approximately 200 ml
How many mL of blood is in a unit?
The volume of one unit of plasma is 200-250 mL. The initial recommended dose for adults is 10 mL/kg, and is 10-15 mL/kg for pediatric patients. Example: 70 kg patient x 10mL/kg = 700 mL (round up to nearest 200mL) = 800 mL = 4 units of plasma.
How much does 1 unit of blood raise hemoglobin?
Abstract. Introduction: Each unit of packed red blood cells (PRBCs) is expected to raise circulating hemoglobin (HGB) by approximately 1 g/dL.
What is the meaning of 1 unit blood?

In general, patients with iron deficient anemia should manifest a response to iron with reticulocytosis in three to seven days, followed by an increase in hemoglobin in 2-4 weeks.
What is the fastest way to increase red blood cells?
5 nutrients that increase red blood cell counts
- red meat, such as beef.
- organ meat, such as kidney and liver.
- dark, leafy, green vegetables, such as spinach and kale.
- dried fruits, such as prunes and raisins.
- egg yolks.
What are the symptoms of low hemoglobin?

- a tingling or crawling feeling in the legs.
- tongue swelling or soreness.
Which fruit is increase blood?
Fruits: Raisins, prunes, dried figs, apricots, apples, grapes and watermelons not only get the red blood cells flowing but also improve the blood count. Citrus fruits like oranges, amla or Indian gooseberry, lime and grapefruit help to attract iron. They play a very important role in increasing blood count.
What foods to avoid if you have low hemoglobin?
Foods to avoid
- tea and coffee.
- milk and some dairy products.
- whole-grain cereals.
- foods that contain tannins, such as grapes, corn, and sorghum.

Diseases and conditions that cause your body to produce fewer red blood cells than normal include: Aplastic anemia. Cancer. Certain medications, such as antiretroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions.
What fruit juice is high in iron?
Each cup of prune juice provides 3 milligrams of iron, and a cup of tomato, carrot, grapefruit, pineapple or mixed vegetable juice supplies 1 milligram. Fruits and vegetables contain the less absorbable form of iron called non-heme iron, but vitamin C, which is in many fruits and vegetables, helps your body absorb more …
