After I got my foldscope last month I watch different type of plant cell. Yesterday I check foldscope field guide found about blood cell. So I pricked my finger with syringe needle and took a drop of blood then put a cover slip on it.

 I put it under foldscope and attached light module and mobile with it.

 The picture wasn’t clear enough and I didn’t see any blood cells in it. So I tried a different way. I took some blood spread it in the slide and dried it.

</ul>

 I then put it under foldscope.

 It wasn’t clear enough so I zoom it a little more with mobile

 Now I can blood cells but can’t identify red or white blood cells because I don’t have any stain
