The Basics
What is Sodium Chromate Cr 51?
Used to determine red blood cell volume or mass, study red blood ceW survival time (in conditions such as hemolytic anemia), and evaluate blood loss.
Brand names for Sodium Chromate Cr 51
Na
How Sodium Chromate Cr 51 is classified
Radiopharmaceuticals, Chromium Radioisotopes, Diagnostic Agents
Sodium Chromate Cr 51 During Pregnancy
Sodium Chromate Cr 51 pregnancy category
Category N/ANote that the FDA has deprecated the use of pregnancy categories, so for some medications, this information isn’t available. We still think it’s useful to list historical info, however, given what a common proxy this has been in the past.
What we know about taking Sodium Chromate Cr 51 while pregnant

Taking Sodium Chromate Cr 51 While Breastfeeding
What are recommendations for lactation if you're taking Sodium Chromate Cr 51?
Information in this record refers to the use of sodium chromate Cr 51 as a diagnostic agent. No information is available on the use of sodium chromate Cr 51 during breastfeeding. The manufacturer recommends withholding breastfeeding after a diagnostic dose of sodium chromate Cr 51, but does not provide a specific duration. The long biological and physical half-lives of chromium may preclude resumption of breastfeeding of the infant. Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital and when the radioactivity is at background levels they may safely resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[1]
