Dear Markus, I recommend you see a NBM 200 (OrSence, Israel). I have no experience with this device, but I saw it presentation at several exhibitions. http://www.orsense.com/product.php?ID=46

Dear Gregory,

Thank you very much. Will do.

Best,

Markus

Dear Markus, the Irish blood transfusion service are currently rolling out implementation of the MBR Haemospect non-invasive device in their blood donation centers following an initial assessment in 400 donors

You can find more details on the device here: http://www.mbr-optical-systems.com/en/haemospect-product.htm

Thanks Anna,

great idea.

Best,

Dear Markus,

I send the data (unpublished) of an our study which compare two non invasive devices: Pronto 7 (Masino), NBM 200 (Orsense) with HemoCue 301 (in use) and LH 750 Coulter (gold standard).. We have tested 412 donors (262 men and 159 women) on september 2011) and 465  (286 men and 179 women) on november 2011. the data from Pearson correlation are: HemoCue vs Coulter: 0.83 in both series, Pronto 7 vs Coulter: 0.69, NBM vs Coulter: 0.57. But Pronto 7 under value the Hb and it determine the deferral of 35% donors (vs 20% for NBM 200 and 6% for HemoCue). Moreover non invasive system are very appreciated from donors and thus in our institution if the value of Hb from NBM is different (1.5-2.0 gr/dL) vs the previous values from Coulter (data available on line), then we use HemoCue 301 and we conside this value for donation or not.

On 2013  we have verified this approch and we have a good result.

I send you the results of this control.

Dear Giovanni,

Thank you very much for sharing your very important data.
