water has the wrong biochemcal properties for the cells within the blood and so they will lyse (cell wall disruption)
A bilirubin specimen is collected through a simple blood test usually performed by using a needle to draw blood from a vein in your arm. The sample is then sent to a laboratory for analysis to measure the levels of bilirubin in the blood.
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.
It is not ideal to isolate DNA from pus collected from bandages as it may contain contaminants from the wound environment. Using white blood cells obtained from a blood sample would provide a purer source of DNA for isolation techniques. This can be done by extracting white blood cells from the blood sample and isolating DNA from these cells using appropriate methods.
Ochre top blood is collected for a variety of tests, primarily related to diagnosing and monitoring certain health conditions. The specific tests often include assessments of liver function, kidney function, and certain metabolic markers. The term "ochre top" refers to the color of the blood collection tube used, which typically contains specific additives that preserve the blood sample for these analyses. Proper collection and handling are crucial for accurate test results.
1. You collect the sample from the nest near the house in the woods in Jersey.2. You take the helicopter back to Mews' lab.3. Once there, you take the egg shell sample form the items bag.4. A screen should pop up showing a bunch of supplies and a tv screen.5. Follow the instructions shown on the screen.

When performing a phenylketonuria (PKU) test, a blood sample is typically collected from a heel prick in newborns. This sample is usually taken within the first week of life to ensure early detection of PKU, a genetic disorder that affects metabolism. The blood is often collected on a special filter paper for laboratory analysis.
It can be used to identify the criminals easily if the criminal's hair sample or blood sample is collected and comparing it with the DNA of the suspects
A sample of the donator's blood is collected at the time of donation and tested for infectious diseases. Blood is not used until the results from these tests confirm that it is safe.
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.
Blood is collected in a plain tube to obtain a serum sample. The absence of additives in a plain tube allows blood to clot naturally, separating the liquid serum from the solid components of the blood. This serum can then be used for various diagnostic tests.
A bilirubin specimen is collected through a simple blood test usually performed by using a needle to draw blood from a vein in your arm. The sample is then sent to a laboratory for analysis to measure the levels of bilirubin in the blood.
No. Your doctor will write a request form for the lab to test your sample (blood, urine, faces, swab etc). Depending on the test you may need to collect the sample yourself e.g. urine or stool sample. If it is a blood test, you will need to go to phlebotomy at your local hospital to have a sample of blood collected. However, some nurses at your local surgery may do this. For biopsies of skin or complex procedures you may need to attend a specialised clinic to have the sample collected. A prescription is only for medication. Not for a laboratory test.
to prevent the red blood cells from digesting the glucose in the sample, true or false?
When blood is collected, separating serum from cells quickly helps prevent clotting or changes in the composition of the sample due to cell degradation. This ensures accurate test results by preserving the integrity of the serum sample for analysis.
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.
