Do you know what is Pseudohaematuria? Pseudohaematuria can be due to dragonfruit ingestion
Have you eaten Dragon fruit lately? If you gorge on the stuff, be warned. Ingestion of Dragon fruit can cause a reddish discoloration of your urine and stool. This was discussed in the Dobbs forum recently, and for the unwary I guess it could be quite alarming. A quick Google search shows that local medical bloggers have already mentioned this.

Jellio also had a similar personal encounter.

Some other foodstuff which can discolor your urine: beetroot blackberries other naturally red foods carrots
Other causes of discolored urine: Medications (e.g. some laxatives, certain antibiotics eg rifampicin and some anti cancer drugs like anthracyclines)
Dyes Reddish discoloration of urine may of course be due to blood (haematuria) or haemoglobin (haemoglobinuria). Urine may be dark or tea colored in liver disease.

As always, you should consult your doctor, especially if there is any doubt.
