A lavender/purple top tube is typically used for renal function tests. This tube contains the anticoagulant EDTA, which helps preserve the blood sample for testing.

A green-top tube (heparin) is typically used for collecting blood samples for a renal function panel. However, it is always recommended to check with the specific laboratory or healthcare provider for their preferred tube color and collection procedures.
The ureter is a collapsible muscular tube that carries urine from the renal pelvis to the bladder.
The glomerulus are a network of capillaries surrounding the renal tube. peritubular capillary beds
The tube connecting the renal hilus of the kidney to the bladder is the ureter. In the renal hilum the ureter, renal blood vessels and nerves enter or exit the kidney.

A renal panel is typically drawn in a green or tiger-top tube, which contains a gel separator to separate serum from cells after centrifugation. It is important to follow the specific instructions of the laboratory or facility where the blood test is being done.
From the renal corpuscle (first the afferent arteriole feeds the glomerulus, which is then drained by the efferent arteriole) and passes on to the renal tubules (passes into the proximal convoluted tube, into the descending and ascending loops of Henle, and the distal convoluted tube)
It is best to wear a red top color for a renal panel blood test as it helps to keep a standard and supports the labs in generating accurate results.
