An in-home lateral flow assay test strip that can be used to monitor PdG levels in urine, which correlate with progesterone levels in serum. The lateral flow test strip is a competitive assay comprising a sample pad, conjugate pad, membrane strip, backing card, an adsorbent pad, a test line impregnated onto the membrane strip comprised of pregnanediol glucuronide (PdG) conjugated to immunoglobulin G (IgG), bovine serum albumin (BSA), bovine gamma globulin (BGG) or another suitable carrier protein and a control line impregnated onto the membrane strip comprised of anti-mouse antibodies. The conjugate pad is saturated with mouse monoclonal anti-PdG antibodies conjugated to colloidal gold, latex beads, or similar visual dye. The test strip may be encased in a cassette such that only the wicking pad and detection zone are visible to the user.
