Reagent Blank : Take reagent and add deionised water (in place of sample to be tested). Now measure the OD at specific wavelength --> this OD is your reagent blank. Substract this OD from your test result (with sample) to avoid any false +ve effect due to colour of reagents itself.Sample Blank : Take sample and measure the OD without adding reagents --> this OD is your sample blank. Substract this OD from your test result to avoid any false +ve effect due to colour and turbidity of sample itself. As it is the fact that colour and turbidity of each sample would vary from one to another.So now it is clear that Reagent blank is used to avoid bias due to colour of reagents and Sample blank is used to avoid bias due to sample itself.
Activated Partial Thromboplastin Time (APTT) is a blood test that measures the time it takes for blood to clot, specifically assessing the intrinsic and common coagulation pathways. It is significant in diagnosing bleeding disorders, monitoring anticoagulant therapy (such as heparin), and evaluating the functionality of clotting factors. Abnormal APTT results can indicate conditions such as hemophilia or the presence of lupus anticoagulants, which may increase the risk of bleeding or thrombosis.
a sample is a sample sized piece given... a sample size is the amount given in one sample
To collect a shallow sample more than 10 feet from the water's edge, a split spoon sampler would be a suitable choice. This sampler is designed for retrieving soil samples from various depths and can effectively collect undisturbed samples in shallow areas. A Traer Kim her bottle or a pump sampler may not be as effective for this specific purpose.
An experimental sample is an experiment that is just a sample of what you are looking for.
Because a plastic bottle can contaminate the sample; and a glass bottle is fragile.
Therapeutic range for aPTT is 45-75 seconds.
A blue-top tube (citrate tube) is used for collecting blood samples for the activated partial thromboplastin time (APTT) test.

The color of the tube commonly used for APTT (Activated Partial Thromboplastin Time) is light blue.
The color of iodine in the bottle is typically purple or brown.
Shaking the sample before transferring it into a sterile McCartney bottle helps to ensure homogeneity of the sample, allowing for a representative portion to be transferred. This helps to minimize sampling errors and ensures accurate analysis of the sample. Additionally, shaking the sample helps to resuspend any settled particles or components, leading to a more uniform distribution in the McCartney bottle.
aptt is 100 seconds

No, you do not need to empty the boric acid from a urine sample bottle before use. The boric acid acts as a preservative to keep the sample stable until it can be tested.
A low APTT result may suggest a bleeding disorder caused by factors like deficiencies in clotting factors (such as hemophilia) or the presence of inhibitors to clotting factors. Further evaluation is necessary to determine the specific cause of the prolonged APTT.
A collecting bottle is a container used for collecting liquid or gas samples during an experiment or testing process. The bottle is typically connected to a sampling device, such as a pipette or pump, which allows the precise transfer of the sample into the bottle without contamination. Once the sample is collected, the bottle can be sealed to preserve the sample for further analysis.
