Corona - Covid19 statement

Several members have asked for guidance on handling DBS cards from infants from potentially infected mothers. There is evidence that in properly dried blood samples the virus does not survive (see https://www.thelancet.com/journals/lanmic/article/PIIS2666-5247(20)30003-3/fulltext). Of course, as always, the usual precautions on handling biological materials should be taken.

About Kevin Alexander (in his own words)

I'm an adult living with PKU. I'm also a professional videographer, and since 2012 I've been traveling the world as a PKU and newborn screening advocate. I'm a volunteer for the National PKU Alliance, Vice President of the Louisiana Metabolic Disorders Coaltion, and a member of the International Society of Neonatal Screening.

Two historic, very interesting, videos on PKU now available!

The Laboratory of Newborn Screening of Catalonia from Hospital Clínic of Barcelona (Spain), via Dr Ana Argudo-Ramírez,  kindly made available to ISNS two historic videos.
The first one shows the original bacterial inhibition assay method for PKU, galactosemia etc. using the Phillips Punch Index Machine. This video was acquired and brought to Barcelona in 1968 by Prof. Juan Sabaté Tobella who was doing a training in the laboratory at Massachusetts General Hospital, where he learned the Guthrie method with Dr. Vivian Shi, director of the laboratory.

The second one concerns a TV show about PKU presented by Dr. Leonard Taitz, possibly made in the '80s.

If the videos will not open in your usual webbrowser please try another one.
