The Preclinical Research Unit (PRU) technicians are proficient at a variety of blood collection methods in laboratory rodents.<\/span><\/span><\/p>\n

Withdrawal Frequency<\/h2>\n

While there are several acceptable methods of rodent blood collection, each method has advantages and disadvantages. Chronic blood withdrawal requires strict limits on obtained volumes and careful consideration for study time-points. The PRU can provide whole blood, plasma or serum.<\/p>\n

Acute Blood Withdrawal<\/h2>\n

The maximum allowable amount of blood withdrawn for an acute withdrawal is 1% of the lean body weight.<\/p>\n

Chronic Blood Withdrawal<\/h2>\n

The maximum allowable amount of blood withdrawn for chronic withdrawals is 1.5% of lean body weight within a 14-day period.<\/p>\n
