TEST NAME	SPECIMEN REQUIREMENT （ｍL）	CONTAINER	CAP COLOR	STORE TEMPERATURE (STABILITY)	TURNAROUND TIME (DAY)	METHODOLOGY	REFERENCE RANGE (UNIT)
Sodium (Na)	Serum 0.5	S09 ↓ A00		（1 month）	2-4	Electrode method Electrode method A method that utilizes a charge transfer reaction at the electrode and solution interface. Ion-selective electrodes respond to specific ions and measure the ion concentration from the potential difference that occurs in proportion to the logarithm of the ion's activity.	136-147 (mEq/L)
Sodium (Na)	Urine storage 0.5	U00			2-4	Electrode method Electrode method A method that utilizes a charge transfer reaction at the electrode and solution interface. Ion-selective electrodes respond to specific ions and measure the ion concentration from the potential difference that occurs in proportion to the logarithm of the ion's activity.	1.6-5.8 (g/day)
K (potassium)	Serum 0.5	S09 ↓ A00		（1 month）	2-4	Electrode method Electrode method A method that utilizes a charge transfer reaction at the electrode and solution interface. Ion-selective electrodes respond to specific ions and measure the ion concentration from the potential difference that occurs in proportion to the logarithm of the ion's activity.	3.6-5.0 (mEq/L)
