Science Buddies: "Ask an Expert"

Hi i need urgent some help

Today I was meant to be gathering all my resources for the Lactose Intolerance experiment I am to do. --> https://www.sciencebuddies.org/science- ... W&fave=yes

But upon going to the local pharmacy, the pharmacist said they did not know or sell
- lactase drops

and that hardly anyone uses Glucose test strips for urinalysis..... ?

he also said that a suitable substitute for Glucose tablets was Barley Sugar - i thought sugar catagorised under sucrose ?

This has been a major set back for my experiment. And I live in New Zealand btw. I really wanted to do this experiment!!
- I am wondering if I can substitute Glucose tablets for Barley sugar, or just use High Energy Glucose instead.
- Whether a product called "Ketostix" which is a reagent strip for urinalysis is a subsitute, though on the back says it has KETONE acid ?
- And if i can buy lactase drops anywhere

Im so confused and upset

Thank you so much,
Jasmeer. x

Dear Jasmeer,
Seems like you need materials for your experiment. I think that if you get diabetic testing strips they would be ok. You can defintely use glucose tablets and use lactose tablets for your lactase drops. Make sure you keep the same concentration when you dissolve the tablets for your experiment. You can order the kit online but it is only shipped in the U.S.A. so I am not sure about New Zealand.

Hi Jay,
Thank you for the reply, It really means a lot.... I was very worried about substituting certain materials, but thank you for these great alternatives. I can easily access diabetic test strips and glucose. I'm not sure about lactase tablets, but I will be sure to go to the pharmacy tomorrow. I also looked at the kit online, but the shipping and handling fee was hundreds of dollars , which is unaffordable.

Thank you for the help again,
Jasmeer xo
