Microalbumin
Small amounts of protein in the urine that cannot be detected by the usual "dipstick" test done for routine urinanalysis testing for other reasons. Specialized dipsticks, or urine collections over a period of 12-24 hours, are used to measure the amount of microalbumin. If there is persistent microalbumin over several repeated tests at different times, the risk of diabetic nephropathy and macrovascular disease are both higher.

Micropenis
A birth defect in which the penis is extremely small. The maximum stretched length is not greater than .5 standard deviation units (SDU) below the mean for age, and possibly as small as 5.0 SDU below. The diameter is correspondingly small, with extreme hypoplasia of the corpora cavernosa. As compared with a micropenis, the average adult penis's stretched length is 6.6 inches (16.7 cm), with a standard deviation of 0.77 inches ([1.95 cm) (Money, Lehne, and Pierre-Jerome, 1984) an exceptionally small penis that resembles the clitoris in size. A micropenis may carry the urethral tube or may be hypospadiac. Typically, it is formed mostly of skin, the body (corpora cavernosa) of the penis being hypoplastic. The condition is also known as microphallus or penile agenesis.
Microphallus

In other words, requiring a microscope to examine.
