What does SG mean on Multistix?
Siemens Multistix 10 SG reagent strips are firm plastic strips to which are affixed several. separate reagent areas. Multistix 10 SG strips provide tests for glucose, bilirubin, ketones, specific gravity, blood, pH, protein, urobilinogen, nitrite, and leukocytes in urine.
What indicates a UTI on a dipstick?
Guidance from PHE [PHE, 2017] states that if dipstick is positive for nitrite or leukocyte and red blood cells (RBC) UTI is likely; if urine dipstick is negative for nitrite and positive for leukocyte, UTI is equally likely to other diagnoses; and if urine dipstick is negative for all nitrite, leukocyte and RBC UTI …
What does SG mean on a urine test strip?
Definition. Urine specific gravity is a laboratory test that shows the concentration of all chemical particles in the urine.
Are Multistix accurate?
Multistix 10 SG urinalysis strips are an effective “rule-out” tool for patients with suspected UTI. In 93% of cases, a negative Multistix 10 SG strip result for leukocyte and nitrite was confirmed negative by urine culture.
What is the average pH of urine?

How accurate is dipstick urinalysis?
A positive urine dipstick has a great chance of being false positive. The average of the positive predictive value in the studies shows 61 percent. However, a negative urine dipstick seems to be more reliable, in which the negative predictive value shows an average of 83 percent.
What does SG 1.030 mean?
Specific gravity. Normal: 1.005–1.030 footnote 1. Abnormal: A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
What does SG 1.030 in urine mean?
Ideally, urine specific gravity results will fall between 1.002 and 1.030 if your kidneys are functioning normally. Specific gravity results above 1.010 can indicate mild dehydration. The higher the number, the more dehydrated you may be.
Why is urine pH high?
A high urine pH may be due to: Kidneys that do not properly remove acids (kidney tubular acidosis, also known as renal tubular acidosis) Kidney failure. Stomach pumping (gastric suction)
Is urine pH of 6.0 normal?
Normal urine pH is slightly acidic, with usual values of 6.0 to 7.5, but the normal range is 4.5 to 8.0.
Can a negative Multistix 10 SG strip be confirmed?
In 93% of cases, a negative Multistix 10 SG strip result for leukocyte and nitrite was confirmed negative by urine culture. The number of false negative samples was significantly reduced when combining the leukocyte and nitrite urinalysis results.
How many urine cultures are positive for Multistix 10 SG?
A multicenter study was conducted to identify patients with potential UTIs. There were 1,887 urine specimens tested comparing the leukocyte and nitrite results of Multistix 10 SG urinalysis strips to urine culture. 1 Did You Know? Only 10-15% of urine cultures are confirmed positive.
What is the purpose of the Multistix 10 SG Test?
PURPOSE: Siemens Multistix 10 SG and other various Siemens reagent test strips are used as a screening procedure to monitor carbohydrate metabolism, kidney and liver function, acid-base balance and urinary tract functions. It is recommended that a confirmation microscopic exam
What can Multistix reagent strips be used for?
Urine MULTISTIX analysis interpretation. (These can be bought from my online shop here – Multistix ) Multistix Reagent strips can be used to test urine for glucose, ketones, specific gravity, blood, pH, protein, nitrites and leucocytes. All these are clues to disease of the kidneys, urinary tract and other problems such as diabetes.
