8:31AM Daxor Corporation announces a research study that proves micro samples are feasible for accurate blood volume measurements on infants and small children utilizing the BVA-100 Blood volume analyzer (DXR) 6.84 : The standard blood sample size for adults is between four to five ml and five to six samples are required for a blood volume measurement. This amount is slightly more than one ounce of blood and is an insignificant loss of blood for an adult. For small children and infants, this sample size if repeat measurements were needed, could result in significant blood loss. The accurate measurement of blood loss both during surgery and in critically ill patients is very difficult to obtain.

There are thousands of adults treated in intensive care units who die every year because their physicians are using so-called surrogate or substitute tests. This results in incorrect guesses of a patient's blood volume status. If fluids or blood transfusions are improperly withheld from patients who have extremely low blood volume (hypovolemia), the result can be irreversible organ damage or even death. At the present time the BVA-100 blood volume analyzer is not used for blood volume measurement in infants or small children.

The studies showed that the blood volume analyzer was capable of providing an accurate measurement with a 97.6% concordance between the samples utilizing the usual adult size and the micro samples. This high degree of concordance is strong evidence that the blood volume analyzer can provide accurate measurements in situations where a microscopic dose might be sufficient. Utilizing such a low dose would require modification of the injectate and standards provided for blood volume measurement.
