Rare negative blood is so sought after for research that even though all samples stored in blood banks are anonymized, there have been cases where scientists have tried to track down and approach individual donors directly to ask for blood.<\/p>\n<p>And because Rhnull blood can be considered \u201cuniversal\u201d blood for anyone with rare blood types within the Rh system, its life-saving capability is enormous. As such, it\u2019s also highly prized by doctors\u2014although it will be given to patients only in extreme circumstances, and after very careful consideration, because it may be nigh on impossible to replace. \u201cIt\u2019s the golden blood,\u201d says Dr. Thierry Peyrard, the current Director of the National Immunohematology Reference Laboratory in Paris.<\/p>\n<p>Blood groups are inherited, and Rhnull is known to run in families. <\/p>\n<p>Source: <a href=\"http:\/\/www.theatlantic.com\/health\/archive\/2014\/10\/the-most-precious-blood-on-earth\/381911\/\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/www.theatlantic.com\/health\/archive\/2014\/10\/the-most-precious-blood-on-earth\/381911\/<\/a><\/p>\n\n\n<p>See also:<\/p>\n\n\n\n<h1 class=\"wp-block-heading\"><a href=\"https:\/\/www.rhesusnegative.net\/staynegative\/topics\/what-is-the-rh-deficiency-syndrome\/\">WHAT IS THE RH DEFICIENCY SYNDROME?<\/a><\/h1>\n<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/static.hupso.com\/share\/buttons\/share-medium.png?w=640&#038;ssl=1\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"What is Rh null?\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>","protected":false},"excerpt":{"rendered":"<div style=\"padding-bottom:20px; padding-top:10px;\" class=\"hupso-share-buttons\"><!-- Hupso Share Buttons - https:\/\/www.hupso.com\/share\/ --><a class=\"hupso_toolbar\" href=\"https:\/\/www.hupso.com\/share\/\"><img src=\"https:\/\/static.hupso.com\/share\/buttons\/share-medium.png\" style=\"border:0px; padding-top:5px; float:left;\" alt=\"Share Button\"\/><\/a><script type=\"text\/javascript\">var hupso_services_t=new Array(\"Twitter\",\"Facebook\",\"Pinterest\",\"Linkedin\");var hupso_background_t=\"#EAF4FF\";var hupso_border_t=\"#66CCFF\";var hupso_toolbar_size_t=\"medium\";var hupso_twitter_via = \"datebytype\";var hupso_image_folder_url = \"\";var hupso_twitter_via=\"datebytype\";var hupso_url_t=\"\";var hupso_title_t=\"What is Rh null?\";<\/script><script type=\"text\/javascript\" src=\"https:\/\/static.hupso.com\/share\/js\/share_toolbar.js\"><\/script><!-- Hupso Share Buttons --><\/div>Rh null individuals have no Rh antigens (no Rh or RhAG) on their red blood cells.
