Changing the world with blood tests

Dear 5/6W,

Today we are looking at the youngest billionaire in the world. This is your opportunity to write a letter to Elizabeth Holmes. You will need to post your letter below and be willing to receive feedback on your writing.

Here is some more information about what she has done in her life…

A standout member among the new-editions to this very elite club is 30-year old college dropout Elizabeth Holmes. Holmes reportedly “labored in secret” for almost a decade while developing a revolutionary new blood-testing technology. In 2003 she took her findings to the public and founded Theranos– the company announced partnerships with Walgreens and other major drugstores to bring a new type of blood testing to consumers. Holmes’ technology calls only for a single finger-prick and a very small amount of blood for medical testing—as opposed to the full vial (or vials) of blood typically drawn for testing in most labs and medical offices. The prick is said to be painless and Theranos’ testing-methods only a fraction of the cost of commercial labs.
The biotech founder is the youngest self-made woman on the Forbes 400 list with a net worth of $4.5 billion. Holmes dropped out of Stanford University her sophomore year as a chemical engineering major and used her tuition money to found her company. Holmes’ tests do not have to be performed in a doctor’s office, and by skipping the big labs most results can be ready in a few hours. “She could totally overturn an entire industry if Theranos is as successful as it seems to be,” says Brown.

    Dear Elizabeth Holmes,
    My name is Alana and I am a year 6 student at St Michael’s. This term we are learning about economics and have been looking at four self made billionaires which are Sara Blakely, Bill Gates, Mark Zuckerberg and yourself! I am very interested in what you have done and i would like to know how you got to where you are today.

    Dear Elizabeth Holmes,
    I love the work that you are doing because i hate needles. Needles hurt and are really scary, needles take lots of blood which your way of taking blood only takes a little bit of blood.

  5. Eliza

    Dear Elizabeth Holmes,
    My name is Eliza and I am at year six at St.michaels primary school in Ashburton in Australia. This term we are learning about economics, we have been given four people that we will be focusing on this term. Those people are Sara Blakely, Bill Gates, Mark Zuckerberg and you!
    I found it really interesting that you hate needles, but still managed to invent a new way to take blood with out being traumatised by the amount of blood been taking out.
    I have a question for you, How long did it take to invent a new way to take blood and how did you get the idea?
    Yours sincerly, Eliza
