The links that Factor X and Factor V follow are misleading. Factor X is hemin and Factor V is nicatinamide adenine dinucleatide. These are not the same factors as in the coagulation cascade.
Haemophilus actually grows better on Chocalate agar and not at all on Blood agar (unless it is satelliting a beta hemolytic colony) The 2 factors Haemophilus needs are within the RBC but it lyse the RBC to get it out. That is why Chocalate Agar is better because it is made with lysed RBC that have all the factor X and V released. Limited speciation can also be done with Haemophilus quad-plates. The external link "Baron's Medical Microbiology" listed in the article discusses Haemophilus's inability to grow on BA. 69.150.225.130 (talk) 22:07, 15 December 2011 (UTC)
Text quote: "Members of the Haemophilus genus will not grow on blood agar plates, as all species require at least one of these blood factors for growth: hemin (factor X) and/or nicotinamide adenine dinucleotide (factor V)." But there is also an image with text: "Haemophilus influenzae on a blood agar plate." — Preceding unsigned comment added by 92.55.149.50 (talk) 05:58, 20 June 2015 (UTC)
