Sodium Chromate 51

Per your order, we have compounded Chromium 51 as a sterile intravenous injectable dispensed as 1 mL in a 5 mL vial. The characteristics of this preparation are described below

Sodium Chromate CR 51 Description

AnazaoHealth’s compounded Cr-51 vial is a sterile, non-pyrogenic diagnostic radiopharmaceutical that consists up to 1 mCi of Cr-51 (precalibrated) in a volume up to 5 mL normal saline and 6 mg/mL benzyl alcohol.

Indications and Usage for Sodium Chromate CR 51

Cr51 is indicated for use in determining red blood cell volume or mass, studying red blood cell survival time (in conditions such as hemolytic anemia), and evaluating blood loss

Mechanism of Action

The chromium in this agent is present as the dianionic chromate ion in which form it appears to bind to the red blood cell in two steps, initially by a rapid but reversible attachment to the cell membrane followed by a slower nearly irreversible binding to intracellular hemoglobin and reduction to the anionic state. It has been suggested that the slow rate of uptake is dependent on the rate at which chromate can penetrate the cell membrane. Binding is maintained until the red blood cells are sequestered by the spleen or until elution of the chromium occurs into the plasma. The chromium is then readily excreted mainly in the urine. Once liberated by elution or erythrocyte senescence, chromium 51 is not available for relabeling of red cells.

In normal individuals the erythrocyte survival half-time T ½  as measured by the chromium 51 "random labeling" technique, generally ranges between 25 and 35 days. This apparent short survival time, when compared to the 120 day life span of the red blood cells, is due to the elution of chromium from the cells and to cell damage that probably occurs during the process of withdrawing them from the body and labeling. Subnormal T ½ may be indicative of blood toss, sequestration of red blood cells by the  spleen, or shortened cell viability, as occurs In hemolytic anemia

Contraindications

There are no known contraindications for this preparation

Sodium Chromate CR 51 Dosage and Administration

  • The suggested dose range in the average patient (70kg) is:
