Predicting serum hormone concentration by estimation of urinary hormones through a home-use device
Pattnaik et al.
The finding, in our words
In 20 women providing 73 paired samples across menstrual‑cycle phases, urinary metabolites measured at home correlated strongly with serum hormone concentrations (estradiol R²=0.96, progesterone R²=0.95, LH R²=0.98). When the derived equations were applied to a separate set of 20 users, predicted serum values correlated 0.92–0.94 with actual measurements. This suggests home urine testing could substitute for clinic blood draws in routine fertility monitoring, though the cohort was limited to women with normal cycles.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
All five at-home urine ovulation predictor kits demonstrated high accuracy (92–97%) when compared with blood LH levels, though sensitivity varied widely from 38% to 77% with Clinical Guard the lowest. Patient experience was comparable across kits, though Clinical Guard was slightly less favoured for future use.
This study validated a lateral flow fluorescence assay using quantum dots for saliva and europium nanoparticles for serum to detect cortisol within physiological ranges. The test operates in 15 minutes with a handheld reader, supporting point-of-care and at-home monitoring without a cold chain.
Home DBS sampling gave testosterone results that agreed well with venous blood in men on intramuscular testosterone undecanoate, but showed falsely high values in those using topical gel, likely from skin contamination. Patients preferred home collection for its convenience, suggesting DBS is viable for decentralised monitoring of injectable testosterone if patients are taught proper technique.
Earlobe capillary microsampling of 100-250 µL found good agreement with venous draws for progesterone, concordance 0.911, and 17β-estradiol, concordance 0.919, across menstrual cycles, showing suitability for decentralised monitoring. However, participant-reported burden was not assessed, and further validation is required in elite athletes.
In 46 women under hormone monitoring at Columbia University Fertility Center, oestradiol, LH, FSH, progesterone and hCG measured on routine immunoassays from 400 to 600 microlitres of upper-arm capillary blood collected with TAP Micro Select agreed closely with paired venous results for every analyte, with correlation and concordance high throughout. It is the evidence that puts a self-collected sample inside the daily monitoring of an IVF cycle.
