The phrase "multiple blood samples" is correct and can be used in written English.
It refers to more than one sample of blood that has been collected or taken from a person or animal for testing or analysis. Example: The doctor ordered multiple blood samples to be taken from the patient to determine the cause of their symptoms.
One of the limitations of this study was the inability to collect multiple blood samples for the analysis of C peptide within the two hour sampling period, hence the need to use a simplified method for estimation of beta cell responsiveness.
In addition, pigs allow for multiple blood samples as well as dosimetry assessment during a long period.
The image-derived blood curves were not corrected for the metabolism of [18F]flumazenil because multiple blood samples could not be performed in same mice.
In addition, multiple blood samples can be easily drawn in pigs compared to rodents and biodistribution studies for dosimetry assessments of therapeutic agents can be carried out over a longer period compared to rodents.
We have shown that information from simultaneous MRI-AIF can reduce the bias on Ki estimates and multiple blood samples might not be necessary, as the scaling method with one blood sample performed better when a parameter reflecting the early part of the MRI-AIF is included.
Noise was added using eq. 2 where α set to 0.5,2 and 4. AIF scaling was done using one blood sample obtained at the end of the study, or by fixing A3 and λ3 to their true values assuming they can be determined using multiple blood samples.
The multiple blood sampling that is necessary in pharmacokinetic and toxicokinetic studies are possible, as well as multiparametric monitoring and interventions with equipment used in human clinical settings.
Invasive procedures such as multiple blood sampling and bone marrow sampling are also performed.
For these reasons new prospectively controlled and randomized trials with multiple blood sampling must be performed to confirm our results.
This procedure for multiple blood sampling does not cause any adverse effects (8, 9, 23, 25, 36, 37).
Multiple blood sampling requires additional staff and may be more difficult in the clinical setting or in large-scale studies.
