Semen Analysis
The findings in this slide are normal sperm and amorphous background.	View Page
Abnormal forms There are a number of abnormalities of sperm morphology. Abnormal heads can include enlarged head, double head, round head, constricted head, amorphous head, pinhead, and acute tapering forms. There are also heads with abnormal numbers of vacuoles. Midpiece abnormalities include distended and thin midpiece regions. Abnormal tails include short tails, double, triple or multiple tails, coiled tails, broken tails, or absent tail. Cytoplasmic droplets are also seen in some specimens. These are large regions of cytoplasm just below the head assumed to represent failure of complete sperm maturation or a sign of either toxicity or oxidation. There have also been reports that cytoplasmic droplets may be artifacts from the fixation and staining for morphology analysis.	View Page
Two abnormalities The sperm in the center of the field is a pinhead. The sperm in the lower right has an amorphous head. The sperm in the upper right has a slightly enlarged head but a good acrosome.	View Page

The Urine Microscopic: Microscopic Analysis of Urine Sediment
Common crystals which can be found in acid urine include:(Choose ALL of the correct answers)	View Page
Use the following urinalysis report to answer:The patient was a female and the examination was completed within two hours of collection. Color - light yellow Appearance - slightly turbid Sp. Gravity - 1.009 pH - 8 Glucose (Multistix) - 0 Glucose (Clinitest) - 0 Protein - 1+ Blood - 0 WBC - 5/HPF RBC - 1/HPF Epithelial - 0/HPF Casts - 2 hyaline/LPF Crystals - amorphous urates Bacteria - 2+True or false? The results are abnormal but all results correlate.	View Page
The patient was a female and the examination was completed within two hours of collection. Which of the following findings are inconsistent with the rest of the report?	View Page
Bilirubin Crystals Bilirubin crystals are seen in the urine when the serum bilirubin level is increased. The macroscopic appearance of urine with bilirubin crystals is orange to almost black in color. The crystals themselves appear as gold orange needle-like forms, or as amorphous material.	View Page
Specimen #2 - Adult Male This report indicates that the specimen is normal. The physical characteristics and microscopic tests do not correlate, as 3+ amorphous urates would probably produce a more turbid or cloudy specimen. Amorphous crystals have little clinical significance and may precipitate out of solution with storage temperature changes. Therefore, the results may be reported.	View Page
Normal Crystals Normal crystals include uric acid, calcium oxalate, amorphous urates or phosphates, triple phosphate, ammonium biurate and calcium carbonate.	View Page
Amorphous Urates Amorphous urates appear as dark or yellow red granules while phosphates are white or colorless. The pH of the urine determines the type of amorphous crystals present. They may be urates in acid urine or phosphates in alkaline urine.	View Page
Crystals in Normal Acid Urine Crystals found in normal acid urine include uric acid, calcium oxalate and amorphous urates. This slide shows an example of uric acid crystals.	View Page
Crystals in Normal Alkaline Urine Crystals found in normal alkaline urine include triple phosphate, ammonium biurate, calcium carbonate, amorphous phosphates, and calcium oxalate. This slide shows an example of triple phosphate crystals. These may appear as four to six sided prisms resembling coffin lids. They indicate either stasis of the bladder or a stale sample.	View Page
Which of the following may be found in normal alkaline urine?	View Page
Please identify these crystals occurring in acid urine.	View Page
Which of the following may be found in normal acid urine?	View Page
Bacteria and Amorphous Material A mixture of bacteria and amorphous material is seen in this field. In order to determine the approximate number of bacteria, the amorphous material can be eliminated.	View Page
A urine specimen was delayed in transport to a medical laboratory. Upon examination of the urine sediment, the technologist cannot distinguish between bacteria and amorphous urates. Which of the following reagents would dissolve the crystals?	View Page
Amorphous Urates Amorphous urates can be dissolved in dilute sodium hydroxide. Amorphous phosphates will dissolve in dilute acetic acid. In either case, the bacteria will remain.	View Page
