You stated that a red particle was noticed on urination, I am unsure whether it was seen in the toilet bowl, on wiping or if all of the urine had a reddish tint to it.

Urine can be discolored as a result of infection, medication, trauma, stones, food, toxins, kidney disease and in rare cases cancer.

In many of the cases where red discoloration is seen, it is blood (haematuria) . Haematuria can occur in bladder or kidney infection- associated with increased frequency of urinary and discomfort on urination (2) due to stones in the urinary tract, however this would usually be associated with pain (3) occur in kidney diseases- such as conditions associated with inflammation or impaired function of the kidneys (4) some medications can also cause haematuria (5) strenuous physical activity (6) blood clotting disorder (7) in older persons more serious conditions such as cancers, have to be ruled out

Hematuria is normally confirmed by a simple urine dipstick. If confirmed the doctor may then take a history to try and determine the cause , possible tests that might be done include - urine for microscopy and culture (looking for any bacteria or any other particles in the urine), imaging of the pelvis to look at the kidneys and bladder, cystoscopy to get an inside look at the bladder and blood tests to assess kidney function.
These tests will only be done if considered necessary based on the history and examination. If due to a urinary tract infection, only the culture will likely be done.

Some persons can also pass kidney stones in their urine though these are usually yellow or brown. Kidney stones can form as a result of diet, due to hereditary factors , due to systemic disease or medication.

If it repeats, you should consider visiting your doctor for a urine analysis and examination.

I hope this is helpful to you, feel free to ask any other questions

Ok, the absence of pain would generally rule out infection and in most cases stones ( though some persons pass stones without any problems)

You can see your doctor if it continues.
