Not for this test. It's a lateral flow assay [1]. The urine is absorbed by the strip and then moves along with capillary action. If there is hCG (human chorionic gonadotropin) in the urine, then the it binds to linked-antibodies (often linked to gold atoms) and drags them along, then those antibodies bind to the actual assay and a control assay (antibodies to the antibodies).

I supposed you could make the line words, but they'd be pretty small.
