What else can I help you with?
What is a sample that is taken without bias?
A randomly selected sample.
After 7 minutes a 53 g sample of plutonium decays to 36 g how long will it take for the sample to decay to 13 of its original amount?
It will take 25.0898 minutes, approx.
Why is it important to have a representative sample when doing surveys?
Because without representative sample, your results will not be valid.
How would a PT result be affected if the tube were only half full?
If the tube used for a prothrombin time (PT) test is only half full, it may lead to an inaccurate blood-to-additive ratio, which can compromise the anticoagulant properties of the sample. This dilution can alter the concentration of the anticoagulant, potentially resulting in prolonged or shortened PT results. Thus, a half-full tube may not provide reliable information about the patient's coagulation status. It's essential to ensure proper sample volume for accurate testing.
Why is a sample often used instead of a census?
because its faster and then when you use a sample you can easily make accurate predictions about what would/will happen next
What will happen if the sample without anticoagulant is not tested within three minutes?
clotting
What color tube to use for an iron test?
A lavender/purple top tube (containing EDTA anticoagulant) is typically used for an iron test. This anticoagulant helps preserve the sample for accurate testing.
Is the liquid portion of a specimen collected in a tube containing EDTA is serum?
No, the liquid portion of a specimen collected in a tube containing EDTA is plasma. Serum is the liquid portion of a blood sample collected in a tube without anticoagulant. EDTA is an anticoagulant that prevents blood clotting by chelating calcium ions.
How to obtain serum from a blood sample?
To obtain serum, the coagulated blood is left to clot at room temperature for approximately 15 to 30 minutes. After it is completely clotted, it is rimmed using an applicator stick and then centrifuged for approximately 5-10minutes at 2500 revolutions per minute. Then the supernatant fluid is separated.
What is sodium fluoride the anticoagulant for while drawing blood?
Sodium fluoride is not an anticoagulant but rather a glycolysis inhibitor. It is used in blood collection tubes to prevent the breakdown of glucose in the blood sample, which can affect certain laboratory tests. The anticoagulant commonly used for blood collection is ethylenediaminetetraacetic acid (EDTA) or heparin.
SUPPOSE WE study the CONTINUOUS VARIABLE: "REPAIR TIME of A machine, in MINUTES". where the POPULATION average IS 135MIN. A SAMPLE of 20 OBSERVATIONS of THAT VARIABLE IS TAKEN. IS possible for the SAMPLE MEAN TO BE EXACTLY EQUAL TO 135MIN?
Yes, it is possible for the sample mean to be exactly equal to 135 minutes. This is because the sample mean is calculated by dividing the sum of all the observations by the number of observations. Therefore, if the sum of all the observations is exactly equal to 2700 minutes (135 times 20), the sample mean would be 135 minutes. However, this is highly unlikely to happen.
Test in which anticoagulant is added to venous blood sample and the distance cells fall in the tube over time is determind?
This test is likely the sedimentation rate test, where anticoagulant is added to a venous blood sample and it is placed in a tube to measure how quickly red blood cells settle at the bottom. This test can help indicate inflammation or infection in the body based on the rate of sedimentation.
What does KC stand for in blood test?
KC stands for "potassium citrate," which is a compound used as an anticoagulant in blood tests to prevent the blood sample from clotting.
What is the anticoagulant used in this type of blood test?
The anticoagulant commonly used for blood tests is ethylenediaminetetraacetic acid (EDTA). It helps prevent the blood sample from clotting by binding to calcium ions, which are necessary for the blood to form clots.
What is the half-life of a radioactive sample of bromine-74 in 25 minutes in a 4mg sample?
The half-life of bromine-74 is 25 minutes, which means that in 25 minutes half of the original sample will decay. In a 4mg sample of bromine-74, after 25 minutes you will have 2mg of the original sample remaining.
What color tube do you use for Homocysteine?
The color tube used for Homocysteine testing is typically lavender or purple. This is because it requires an EDTA anticoagulant to preserve the sample.
What color tube for hepatitis antibody immunology?
A red-top tube with no anticoagulant would be appropriate for collecting a blood sample for hepatitis antibody immunology testing.
