Normal urine should be a pale yellow color. It should be clear, without cloudiness or particle deposits. “Why is my urine bright yellow?” is a question that can be answered if the meaning of bright yellow is clear. This page will explain the full range of possible colours of urine and why they change. If bright yellow means neon yellow, this has a specific cause.
Why does urine turn bright yellow?
To answer the question of bright yellow urine color, it may help to cover what it means when urine is really fluorescent bright. Neon yellow urine colour signals too much intake of vitamin B, although this is harmless.
What is the normal colour for urine?
Urine colour is normally pale yellow, but the depth of yellowness can vary healthily. The yellow colour gets darker as the concentration of the urine gets higher. Concentration means the proportion of waste products to water in the urine. The proportion of waste products to water increases and the urine darkens, as less fluid is taken in. This also happens if more fluid is lost by other means such as sweating.
What gives urine its healthy yellow colour?
Researchers using DNA sequencing to profile antibiotic resistance in infection have achieved a turnaround time from ‘sample to answer’ of less than four hours for urinary tract infections (UTIs). The nanopore MinION device is being researched by the University of East Anglia (UEA) as a way to speed up investigation of infection including UTIs – one of the most common reasons patients are prescribed antibiotics. Traditional culture methods take two to three days to characterise bacteria and test their antimicrobial resistances from a urine sample. Early results from the UEA group’s method showed that the Oxford Nanopore Technologies device can characterise bacteria and predict their antimicrobial resistances in just 12 hours from a urine sample. This has now been shortened to as little as four hours, as published in the Journal of Antimicrobial Chemotherapy. While most UTIs are mild, serious cases can lead to hospitalisation. At worst, bacteria can enter the bloodstream causing urosepsis, a life-threatening condition. In this case antibiotics are vital and must be given urgently. Faster prediction of whether the UTI is caused by a highly-resistant type of bacteria will allow precise tailoring of treatment. The patient wil
