pediatric blood draw limits: how much is safe

Posted by Neoteryx on Sep 5, 2018 3:03:00 AM

In pediatric medicine, for screening and other purposes, it is important to know the appropriate amount of blood that can be drawn from a child depending on their age. The younger they are, the less their blood volume. In cases of newborn screening, if too much blood is drawn, there is a risk of losing an infant.

safety concerns in finger-stick capillary blood sampling

Posted by Neoteryx on Apr 17, 2018 8:02:00 AM

Capillary finger-prick blood draws have gained popularity. This is partly in response to innovations in point of care testing and remote sampling. Capillary blood has distinct advantages in hospital labs, clinical labs, and in other circumstances requiring on-site sampling and other more traditional blood collection practices. An ongoing quest to streamline workflows and make them more efficient has led to a reconsideration of dried blood spot sampling.

is dried blood a biohazard?

Posted by Neoteryx on Apr 9, 2018 6:06:00 AM

Working with traditional wet blood specimens has always raised safety concerns and posed logistical challenges. Blood sample storage and cold chain shipping require navigating an increasingly complicated maze of regulatory issues. It's no wonder that dried blood spotting has emerged in the last few decades as a preferable alternative in many cases.

5 common capillary puncture sites

Posted by Neoteryx on Jan 23, 2018 5:15:00 AM

Capillary blood sampling is becoming a common way to minimize the amount of blood drawn from a patient. The 10 or 20 microliters can be used to look for anemia, check blood sugar or even to evaluate thyroid function. The procedure is easier and less painful than traditional venipuncture which draws blood from a vein.

how to use capillary blood samples in pediatric PK studies

Posted by Neoteryx on Dec 5, 2017 6:10:00 AM

Pharmacokinetic (PK) studies investigate the absorption and movement of drugs within the body. Since children absorb and process drugs differently than adults do, PK studies have to be done on children to determine safe and effective doses.
